TipcMsgAppendReal8Array

TipcMsgAppendReal8Array — append a field containing an array of REAL8 fields to a message

Synopsis

T_BOOL TipcMsgAppendReal8Array(msg, real8_array_data, array_size) 
T_IPC_MSG msg; 
T_REAL8 *real8_array_data; 
T_INT4 array_size;

Arguments

Return Values

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

Diagnostics

If TipcMsgAppendReal8Array fails, it returns FALSE and sets the global SmartSockets error number to one of:

T_ERR_NULL_PTR — msg was null or real8_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

TipcMsgAppendReal8Array appends an eight-byte real number array (REAL8_ARRAY) field containing real8_array_data to the end of a message’s data. TipcMsgAppendReal8Array makes a copy of the array data.

Examples

T_IPC_MT mt; 
T_IPC_MSG msg; 
T_REAL8 data[2]; 
 
#define USER_MT_REAL8_ARRAY_TEST 100 
mt = TipcMtCreate("real8_array_test", USER_MT_REAL8_ARRAY_TEST,  
                  "real8_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] = 56.1; 
data[1] = 57.2; 
if (!TipcMsgAppendReal8Array(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. */
