TipcMsgAppendInt4Array

TipcMsgAppendInt4Array — append a field containing an array of INT4 fields to a message

Synopsis

T_BOOL TipcMsgAppendInt4Array(msg, int4_array_data, array_size) 
T_IPC_MSG msg; 
T_INT4 *int4_array_data; 
T_INT4 array_size;

Arguments

Return Values

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

Diagnostics

If TipcMsgAppendInt4Array fails, it returns FALSE and sets the global SmartSockets error number to one of:

T_ERR_NULL_PTR — msg was null or int4_array_data 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

T_ERR_VAL_TOO_SMALL — array_size was negative

Description

TipcMsgAppendInt4Array appends a four-byte integer array (INT4_ARRAY) field containing int4_array_data to the end of a message’s data. TipcMsgAppendInt4Array makes a copy of the array data.

Examples

T_IPC_MT mt; 
T_IPC_MSG msg; 
T_INT4 data[2]; 
 
#define USER_MT_INT4_ARRAY_TEST 100 
mt = TipcMtCreate("int4_array_test", USER_MT_INT4_ARRAY_TEST,  
                  "int4_array"); 
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. */ 
 
data[0] = 560000; 
data[1] = 570000; 
if (!TipcMsgAppendInt4Array(msg, data, 2)) { 
  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. */
