SetInputStream Method
Sets the stream from which the class will read data to sign or verify.
Syntax
ANSI (Cross Platform) int SetInputStream(IPWorksEncryptStream* sInputStream); Unicode (Windows) INT SetInputStream(IPWorksEncryptStream* sInputStream);
#define MID_XMLSIG_SETINPUTSTREAM 5 IPWORKSENCRYPT_EXTERNAL int IPWORKSENCRYPT_CALL IPWorksEncrypt_XMLSig_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);
Remarks
This method sets the stream from which the class will read data to sign or verify. If an input stream is set before calling Sign or VerifySignature, the data is read from the input stream instead of from the InputFile or InputXML properties.
The content of the stream will be read from the current position all the way to the end and no bytes will be skipped.
Input and Output Properties
The class will determine the source and destination of the input and output based on which properties are set.
The order in which the input properties are checked is as follows:
When a valid source is found the search stops. The order in which the output properties are checked is as follows:- OutputFile
- OutputXML: The output data is written to this property if no other destination is specified.
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.)
