TipcMsgAppendBool

T_BOOL TipcMsgAppendBool(msg, bool_data) 
T_IPC_MSG msg; 
T_BOOL bool_data;

Arguments

Return Values

TRUE if the field was successfully appended to the message, FALSE otherwise.

Diagnostics

If TipcMsgAppendBool fails, it returns FALSE and sets the global SmartSockets error number to one of:

T_ERR_NULL_PTR — msg was null

T_ERR_READ_ONLY — the message was marked read-only. This happens if the message is a field in another message.

T_ERR_MSG_INVALID — msg was not a valid message

Description

TipcMsgAppendBool appends a BOOL field containing bool_data to the end of a message’s data.

T_IPC_MSG mt; 
T_IPC_MSG msg; 
 
#define USER_MT_BOOL_TEST 100 
mt = TipcMtCreate("bool_test", USER_MT_BOOL_TEST,  
                  "bool"); 
if (mt == NULL) { 
  return;  /* error */ 
} 
 
msg = TipcMsgCreate(mt); 
if (msg == NULL) { 
  return;  /* error */ 
} 
 
/* An RTclient would typically set the destination of */ 
/* a message at this point by calling TipcMsgSetDest. */ 
 
if (!TipcMsgAppendBool(msg, T_TRUE)) { 
  return;  /* error */ 
}  
 
/* A process would typically send a message at this point by */ 
/* calling TipcConnMsgSend or TipcSrvMsgSend. */ 
 
/* A process would typically destroy a message at this point by */ 
/* calling TipcMsgDestroy. */
