SendKeepAlive Method

Sends a keep-alive message.

Syntax

ANSI (Cross Platform)
int SendKeepAlive();

Unicode (Windows)
INT SendKeepAlive();
- (BOOL)sendKeepAlive;
#define MID_WEBSOCKETCLIENT_SENDKEEPALIVE 6

SECUREBLACKBOX_EXTERNAL int SECUREBLACKBOX_CALL SecureBlackbox_WebSocketClient_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

Use this method to send a keep-alive 'ping' to the server. The response, if it comes back, will be reported via the KeepAliveResponse event.

Keep-alive messages provide good means for keeping the connection alive and stay immune to timeouts.

Error Handling (C++)

This method returns a Boolean 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.
