SMPP Class

Properties   Methods   Events   Config Settings   Errors  

The Smpp Class implements a lightweight message transmission interface using the Short Message Peer-to-Peer protocol, most known for its use in cellular text messaging.

Syntax

SMPP

Remarks

The Smpp class supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over SSL/TLS the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL related settings are also supported via the Config method.

The Smpp Class will bind as a transceiver, and thus it can send and receive messages from the server. Additionally, it can send single and multirecipient messages and also can upload data.

Using Smpp is quite easy. First, simply set the SMPPServer, SMPPPort, and, if needed, the SMPPVersion properties. Second, a single call to the Connect method with a specified user Id and password will connect the class.

Transmitting messages is just as easy. You can manipulate the Recipients properties directly, or just use AddRecipient method to add recipients one at a time to the recipient list. After all recipients have been added, a single call to the SendMessage method will transmit the specified message. If the send is successful, the method will set and return the value of the MessageId property. Otherwise, an Error event will fire for each unsuccessful message destination.

The Smpp Class supports message and data transmission, as well as auxiliary operations, such as CheckMessageStatus and ReplaceMessage. All nonimplemented features of the protocol are supported through the SendCommand method and PITrail event. Because of the nature of the protocol, all methods and operations are implemented synchronously.

Default Value

FALSE

Remarks

The value of this property indicates whether or not the class has successfully bound to the SMPPServer. It will not be true until a successful Connected event has fired.

The two ways to bind are (1) by calling Connect with a user identifier and password, which will set the UserId and Password properties before connecting; or (2) by setting those two properties and calling SendMessage while not connected.

Note: It is recommended to use the Connect or Disconnect method instead of setting this property.

This property is read-only and not available at design time.

Default Value

0

Remarks

This is the type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This property can take one of the following values:

Data Type

Integer

SSLCertSubject Property (SMPP Class)

This is the subject of the certificate used for client authentication.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetSSLCertSubject();
int SetSSLCertSubject(const char* lpszSSLCertSubject);

Unicode (Windows)
LPWSTR GetSSLCertSubject();
INT SetSSLCertSubject(LPCWSTR lpszSSLCertSubject);

int ipworks_smpp_setsslcertsubject(void* lpObj, const char* lpszSSLCertSubject);

QString GetSSLCertSubject();
int SetSSLCertSubject(QString qsSSLCertSubject);

Default Value

""

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.

If a field value contains a comma it must be quoted.

Data Type

String

SSLEnabled Property (SMPP Class)

int ipworks_smpp_getsslprovider(void* lpObj);
int ipworks_smpp_setsslprovider(void* lpObj, int iSSLProvider);

int GetSSLProvider();
int SetSSLProvider(int iSSLProvider);

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, on Windows the class will use the platform implementation. On Linux/macOS the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

Data Type

Integer

SSLServerCertEncoded Property (SMPP Class)

This is the certificate (PEM/base64 encoded).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetSSLServerCertEncoded(char* &lpSSLServerCertEncoded, int &lenSSLServerCertEncoded);

Unicode (Windows)
INT GetSSLServerCertEncoded(LPSTR &lpSSLServerCertEncoded, INT &lenSSLServerCertEncoded);

int ipworks_smpp_getsslservercertencoded(void* lpObj, char** lpSSLServerCertEncoded, int* lenSSLServerCertEncoded);

QByteArray GetSSLServerCertEncoded();

Default Value

""

Remarks

This is the certificate (PEM/base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.

When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.

This property is read-only and not available at design time.

Data Type

Binary String

SSLStartMode Property (SMPP Class)

Determines how the class starts the SSL negotiation.

Syntax

• C++
• C
• Qt

Data Type

Integer

SystemType Property (SMPP Class)

This property contains a string representing the type of system during a connection.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetSystemType();
int SetSystemType(const char* lpszSystemType);

Unicode (Windows)
LPWSTR GetSystemType();
INT SetSystemType(LPCWSTR lpszSystemType);

char* ipworks_smpp_getsystemtype(void* lpObj);
int ipworks_smpp_setsystemtype(void* lpObj, const char* lpszSystemType);

QString GetSystemType();
int SetSystemType(QString qsSystemType);

Default Value

""

Remarks

This property contains a string representing the type of system during a connection. Some SMS servers require that a system type be supplied during connection. The system type is a string representation, usually as an abbreviation, of a particular kind of system. The string cannot exceed 12 bytes.

Data Type

String

Timeout Property (SMPP Class)

A timeout for the class.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetTimeout();
int SetTimeout(int iTimeout);

Unicode (Windows)
INT GetTimeout();
INT SetTimeout(INT iTimeout);

int ipworks_smpp_gettimeout(void* lpObj);
int ipworks_smpp_settimeout(void* lpObj, int iTimeout);

int GetTimeout();
int SetTimeout(int iTimeout);

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the class fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

Data Type

Integer

UserId Property (SMPP Class)

This property is used for identification with the SMPP service.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetUserId();
int SetUserId(const char* lpszUserId);

Unicode (Windows)
LPWSTR GetUserId();
INT SetUserId(LPCWSTR lpszUserId);

char* ipworks_smpp_getuserid(void* lpObj);
int ipworks_smpp_setuserid(void* lpObj, const char* lpszUserId);

QString GetUserId();
int SetUserId(QString qsUserId);

Default Value

""

Remarks

This property is used for identification with the SMPP service. When binding to the SMPPServer, the client must provide a known user identifier and a valid password for that Id.

The two ways to bind are (1) by calling Connect with a user Id and password, which will set the UserId and Password properties before connecting; or (2) by setting those two properties and calling SendMessage while not connected.

Data Type

String

AddRecipient Method (SMPP Class)

This method will add a recipient of the specified type to the recipient list.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int AddRecipient(int iRecipientType, const char* lpszRecipientAddress);

Unicode (Windows)
INT AddRecipient(INT iRecipientType, LPCWSTR lpszRecipientAddress);

int ipworks_smpp_addrecipient(void* lpObj, int iRecipientType, const char* lpszRecipientAddress);

int AddRecipient(int iRecipientType, const QString& qsRecipientAddress);

Remarks

This method will add a recipient of the specified type to the recipient list. For normal-type recipients, the addresses should be either a dotted IPv4 address (for sending messages to other SMS-enabled applications) or the directory number of a mobile phone. To send messages to distributed lists, the name of the list should be used.

Valid values for RecipientType are as follows:

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

CancelMessage Method (SMPP Class)

This method will cancel the specified message.

Syntax

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

CheckLink Method (SMPP Class)

This method will check the connection to the server.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int CheckLink();

Unicode (Windows)
INT CheckLink();

int ipworks_smpp_checklink(void* lpObj);

int CheckLink();

Remarks

This method will check the connection to the server. This method is used to ensure that the host on the other end of the connection is still active, or that it is still available. Although a socket connection may still be available between the client and server, the SMS application on the server may have been taken offline without releasing the socket or the CPU may be bogged down. This method will send a PDU to the server and wait the length of Timeout for a response.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

CheckMessageStatus Method (SMPP Class)

This method will retrieve the status of the specified message.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Config Method (SMPP Class)

Sets or retrieves a configuration setting.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* ipworks_smpp_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

QByteArray SendCommand(int iCommandId, QByteArray qbaPayload);

Remarks

This method offers a way to do more with the class than is directly supported. This method takes a command identifier and a payload, which includes every required and optional field after the header, and creates the 16-byte header for it before sending it to the server. The response PDU is returned both in the PITrail and by this method.

Error Handling (C++)

This method returns a Binary String value (with length lpSize); after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

class SMPPConnectedEventParams {
public:
  int StatusCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Connected(SMPPConnectedEventParams *e);

// Or, subclass SMPP and override this emitter function.
virtual int FireConnected(SMPPConnectedEventParams *e) {...}

Remarks

After establishing a socket connection to the SMPPServer, the class will attempt to send a bind as a transmitter command. Upon completion of this operation, the server will respond with either a success or failure state, which will be reflected in the Connected event's parameters.

StatusCode will contain the command status (error code) returned by the server. For a StatusCode of 0, Description will be OK. Otherwise, it will contain a standard interpretation of the error.

ConnectionStatus Event (SMPP Class)

This event is fired to indicate changes in the connection state.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireConnectionStatus(SMPPConnectionStatusEventParams *e);

typedef struct {
  const char *ConnectionEvent;
  int StatusCode;

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void ConnectionStatus(SMPPConnectionStatusEventParams *e);

// Or, subclass SMPP and override this emitter function.
virtual int FireConnectionStatus(SMPPConnectionStatusEventParams *e) {...}

Remarks

The ConnectionStatus event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.

The ConnectionEvent parameter indicates the type of connection event. Values may include the following:

Disconnected Event (SMPP Class)

This event is fired when connection to the SMS service is lost.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireDisconnected(SMPPDisconnectedEventParams *e);

class SMPPDisconnectedEventParams {
public:
  int StatusCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Disconnected(SMPPDisconnectedEventParams *e);

// Or, subclass SMPP and override this emitter function.
virtual int FireDisconnected(SMPPDisconnectedEventParams *e) {...}

Remarks

After sending an unbind operation to the server, this event will be fired containing the results of that operation. This event may also be fired if the socket connection to the service is lost.

If the event was fired because of an unbind operation, StatusCode will contain the command status set by the server. Otherwise, it will contain the socket code for the type of disconnection. For a status code value of 0, Description will contain OK. Otherwise, it will contain a standard interpretation of the value in StatusCode.

Error Event (SMPP Class)

This event is fired when the server detects an error.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireError(SMPPErrorEventParams *e);

// To handle, connect one or more slots to this signal.
void Error(SMPPErrorEventParams *e);

// Or, subclass SMPP and override this emitter function.
virtual int FireError(SMPPErrorEventParams *e) {...}

Remarks

If the server sends an error not related to a command sent from the class, the class will fire an Error event containing information related to the error.

ErrorCode will contain the code sent by the server, and Description will contain a standard interpretation of that code.

MessageIn Event (SMPP Class)

This event is fired upon receipt of a message.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireMessageIn(SMPPMessageInEventParams *e);

typedef struct {
  const char *SourceAddress;
  const char *ScheduleDeliveryTime;
  const char *ValidityPeriod;
  const char *Message;
  int MessagePart;
  int MessagePartCount;
  int MessagePartReference;
  const char *DestinationAddress;
  int ResponseErrorCode;
  int reserved;
} SMPPMessageInEventParams;


Unicode (Windows)
virtual INT FireMessageIn(SMPPMessageInEventParams *e);

typedef struct {
  LPCWSTR SourceAddress;
  LPCWSTR ScheduleDeliveryTime;
  LPCWSTR ValidityPeriod;
  LPCWSTR Message;
  INT MessagePart;
  INT MessagePartCount;
  INT MessagePartReference;
  LPCWSTR DestinationAddress;
  INT ResponseErrorCode;
  INT reserved;
} SMPPMessageInEventParams;

#define EID_SMPP_MESSAGEIN 5

virtual INT IPWORKS_CALL FireMessageIn(LPSTR &lpszSourceAddress, LPSTR &lpszScheduleDeliveryTime, LPSTR &lpszValidityPeriod, LPSTR &lpszMessage, INT &iMessagePart, INT &iMessagePartCount, INT &iMessagePartReference, LPSTR &lpszDestinationAddress, INT &iResponseErrorCode);

class SMPPMessageInEventParams {
public:
  const QString &SourceAddress();

  const QString &ScheduleDeliveryTime();

  const QString &ValidityPeriod();

  const QString &Message();

  int MessagePart();

  int MessagePartCount();

  int MessagePartReference();

  const QString &DestinationAddress();

  int ResponseErrorCode();
  void SetResponseErrorCode(int iResponseErrorCode);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void MessageIn(SMPPMessageInEventParams *e);

// Or, subclass SMPP and override this emitter function.
virtual int FireMessageIn(SMPPMessageInEventParams *e) {...}

Remarks

When a message is received, the SMPP class will parse the sender's message into the SourceAddress, ScheduleDeliveryTime, ValidityPeriod, and Message fields.

The SourceAddress parameter is the address of the originator of the message.

The DestinationAddress parameter holds the address of the recipient.

The ScheduleDeliveryTime parameter is the delivery time at which the short message is scheduled to be forwarded to another Message Center (MC). This will be an empty string if it is not scheduled.

The ValidityPeriod parameter is applicable only if this short message is being forwarded to another MC. When this occurs, it specifies how long the receiving MC should retain the Short Message (SM) and continue trying to deliver it. This will be an empty string if the current validity period is unavailable.

The Message parameter is the plaintext portion of the message body.

If the incoming message is a part of a larger message (the message was split up into several parts), the MessagePartCount, MessagePart, and MessagePartReference parameters will be set. MessagePartCount will hold the total number of parts for the message. MessagePart will indicate the current part's location in the message to determine the order when reassembling the message. This will be a value from 1 to MessagePartCount. MessagePartReference holds a reference value that will be the same across all parts for the message.

The ResponseErrorCode parameter may be set to return an error condition to the server. This corresponds to the command_status protocol-level field of the response.

MessageStatus Event (SMPP Class)

This event is fired upon receipt of a message.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireMessageStatus(SMPPMessageStatusEventParams *e);

typedef struct {
  const char *MessageId;
  int MessageState;
  int MessageError;
  const char *FinalDate;
  int reserved;
} SMPPMessageStatusEventParams;


Unicode (Windows)
virtual INT FireMessageStatus(SMPPMessageStatusEventParams *e);

typedef struct {
  LPCWSTR MessageId;
  INT MessageState;
  INT MessageError;
  LPCWSTR FinalDate;
  INT reserved;
} SMPPMessageStatusEventParams;

#define EID_SMPP_MESSAGESTATUS 6

virtual INT IPWORKS_CALL FireMessageStatus(LPSTR &lpszMessageId, INT &iMessageState, INT &iMessageError, LPSTR &lpszFinalDate);

class SMPPMessageStatusEventParams {
public:
  const QString &MessageId();

  int MessageState();

  int MessageError();

  const QString &FinalDate();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void MessageStatus(SMPPMessageStatusEventParams *e);

// Or, subclass SMPP and override this emitter function.
virtual int FireMessageStatus(SMPPMessageStatusEventParams *e) {...}

Remarks

When a CheckMessageStatus is called, the SMPP class will fetch the status of the message represented by MessageId from the server, parse the response, and fire MessageStatus.

MessageState represents the last known state the message was left in on the SMPPServer. This code is version specific. For v3.4:

MessageError will contain an error code representing any failure encountered during message delivery. This code may be vendor-specific.

FinalDate contains a human-readable string representing the date on which the message was delivered. If the message was not delivered, this parameter will be empty.

PITrail Event (SMPP Class)

This event is fired once for each protocol data unit (PDU) sent between the client and server.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FirePITrail(SMPPPITrailEventParams *e);

typedef struct {
  int Direction;
  const char *PDU;
  int lenPDU;
  int CommandLength;
  int CommandId;
  const char *CommandDescription;
  const char *CommandStatus;
  int SequenceNumber;
  int reserved;
} SMPPPITrailEventParams;


Unicode (Windows)
virtual INT FirePITrail(SMPPPITrailEventParams *e);

typedef struct {
  INT Direction;
  LPCSTR PDU;
  INT lenPDU;
  INT CommandLength;
  INT CommandId;
  LPCWSTR CommandDescription;
  LPCWSTR CommandStatus;
  INT SequenceNumber;
  INT reserved;
} SMPPPITrailEventParams;

#define EID_SMPP_PITRAIL 7

virtual INT IPWORKS_CALL FirePITrail(INT &iDirection, LPSTR &lpPDU, INT &lenPDU, INT &iCommandLength, INT &iCommandId, LPSTR &lpszCommandDescription, LPSTR &lpszCommandStatus, INT &iSequenceNumber);

class SMPPPITrailEventParams {
public:
  int Direction();

  const QByteArray &PDU();

  int CommandLength();

  int CommandId();

  const QString &CommandDescription();

  const QString &CommandStatus();

  int SequenceNumber();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void PITrail(SMPPPITrailEventParams *e);

// Or, subclass SMPP and override this emitter function.
virtual int FirePITrail(SMPPPITrailEventParams *e) {...}

Remarks

Whenever either the class or the SMPPServer sends any data across the connection, the class will fire a PITrail event containing that data. It will usually be in SMPP-PDU format.

A PDU will contain at least the SMPP header, which is always 16 bytes long. The first four bytes represent the total length of the PDU, including the 16-byte header. The next four bytes are the command Id associated with the PDU. The command Id of a response PDU is always the command Id to which it is responding plus 0x80000000.

The class parses the values contained in the PDU header into the appropriate fields. The CommandLength, CommandId, CommandStatus, and SequenceNumber parameters contain these parsed values.

The third set of four bytes are the command status (status code) of the command. All originating commands will have a status code of 0x00000000, which will be ignored by the receiver. The field is only set in response PDUs to indicate the status of the originating command. The final four bytes represent the sequence number of the command. All response PDUs will contain the same sequence number as the originating command.

ReadyToSend Event (SMPP Class)

This event is fired when the class is ready to send data.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireReadyToSend(SMPPReadyToSendEventParams *e);

typedef struct {
  int reserved;
} SMPPReadyToSendEventParams;


Unicode (Windows)
virtual INT FireReadyToSend(SMPPReadyToSendEventParams *e);

typedef struct {
  INT reserved;
} SMPPReadyToSendEventParams;

#define EID_SMPP_READYTOSEND 8

virtual INT IPWORKS_CALL FireReadyToSend();

class SMPPReadyToSendEventParams {
public:
  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void ReadyToSend(SMPPReadyToSendEventParams *e);

// Or, subclass SMPP and override this emitter function.
virtual int FireReadyToSend(SMPPReadyToSendEventParams *e) {...}

Remarks

The ReadyToSend event indicates that the underlying Transmission Control Protocol (TCP)/IP subsystem is ready to accept data after a failed DataToSend. This event also is fired immediately after a connection to the remote host is established.

SSLServerAuthentication Event (SMPP Class)

Fired after the server presents its certificate to the client.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSLServerAuthentication(SMPPSSLServerAuthenticationEventParams *e);

typedef struct {
  const char *CertEncoded;
  int lenCertEncoded;
  const char *CertSubject;
  const char *CertIssuer;
  const char *Status;
  int Accept;
  int reserved;
} SMPPSSLServerAuthenticationEventParams;


Unicode (Windows)
virtual INT FireSSLServerAuthentication(SMPPSSLServerAuthenticationEventParams *e);

typedef struct {
  LPCSTR CertEncoded;
  INT lenCertEncoded;
  LPCWSTR CertSubject;
  LPCWSTR CertIssuer;
  LPCWSTR Status;
  BOOL Accept;
  INT reserved;
} SMPPSSLServerAuthenticationEventParams;

#define EID_SMPP_SSLSERVERAUTHENTICATION 9

virtual INT IPWORKS_CALL FireSSLServerAuthentication(LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);

class SMPPSSLServerAuthenticationEventParams {
public:
  const QByteArray &CertEncoded();

  const QString &CertSubject();

  const QString &CertIssuer();

  const QString &Status();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSLServerAuthentication(SMPPSSLServerAuthenticationEventParams *e);

// Or, subclass SMPP and override this emitter function.
virtual int FireSSLServerAuthentication(SMPPSSLServerAuthenticationEventParams *e) {...}

Remarks

This event is where the client can decide whether to continue with the connection process or not. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK"). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (SMPP Class)

Shows the progress of the secure connection.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSLStatus(SMPPSSLStatusEventParams *e);

typedef struct {
  const char *Message;
  int reserved;
} SMPPSSLStatusEventParams;


Unicode (Windows)
virtual INT FireSSLStatus(SMPPSSLStatusEventParams *e);

typedef struct {
  LPCWSTR Message;
  INT reserved;
} SMPPSSLStatusEventParams;

#define EID_SMPP_SSLSTATUS 10

virtual INT IPWORKS_CALL FireSSLStatus(LPSTR &lpszMessage);

class SMPPSSLStatusEventParams {
public:
  const QString &Message();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSLStatus(SMPPSSLStatusEventParams *e);

// Or, subclass SMPP and override this emitter function.
virtual int FireSSLStatus(SMPPSSLStatusEventParams *e) {...}

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

Trappable Errors (SMPP Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

SMPP Errors

The class may also return one of the following error codes, which are inherited from other classes.

TCPClient Errors
