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_TELNET_KEEPALIVE 15

IPWORKS_EXTERNAL void* IPWORKS_CALL IPWorks_Telnet_Get(void *lpObj, int propid, int arridx, int *lpcbVal, int64 *lpllVal);
IPWORKS_EXTERNAL int IPWORKS_CALL IPWorks_Telnet_Set(void *lpObj, int propid, int arridx, const void *val, int cbVal);

Default Value

FALSE

Remarks

The KeepAlive enables the SO_KEEPALIVE option on the socket. 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.

Data Type
