KeepAlive Property

When True, KEEPALIVE packets are enabled (for long connections).

Syntax

ANSI (Cross Platform)
int GetKeepAlive();
int SetKeepAlive(int bKeepAlive);

Unicode (Windows)
BOOL GetKeepAlive();
INT SetKeepAlive(BOOL bKeepAlive);
@property (nonatomic,readwrite,assign,getter=keepAlive,setter=setKeepAlive:) BOOL keepAlive;
- (BOOL)keepAlive;
- (void)setKeepAlive:(BOOL)newKeepAlive;

#define PID_MLLPSERVER_KEEPALIVE 13

IPWORKSEDI_EXTERNAL void* IPWORKSEDI_CALL IPWorksEDI_MLLPServer_Get(void *lpObj, int propid, int arridx, int *lpcbVal, int64 *lpllVal);
IPWORKSEDI_EXTERNAL int IPWORKSEDI_CALL IPWorksEDI_MLLPServer_Set(void *lpObj, int propid, int arridx, const void *val, int cbVal);

Default Value

FALSE

Remarks

This property enables the SO_KEEPALIVE option on the incoming connections. This option prevents long connections from timing out in case of inactivity.

Please note that system TCP/IP stack implementations are not required to support SO_KEEPALIVE.

This property is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified.
