TipcMsgUpdateNamedReal4Array

TipcMsgUpdateNamedReal4Array — update a field containing an array of REAL4 fields in a message with new data

T_BOOL TipcMsgUpdateNamedReal4Array(msg, name, value, size) 
T_IPC_MSG msg; 
T_STR name; 
T_REAL4 *value; 
T_INT4 size;

msg — message to update field in

name — name of the field

value — value of the field

size — number of elements in the field

TRUE if the update was successful, FALSE otherwise.

If TipcMsgUpdateNamedReal4Array fails, it returns FALSE and sets the global SmartSockets error number to one of:

T_ERR_NULL_PTR — msg, name or value is null

T_ERR_MSG_INVALID — msg was not a valid message

T_ERR_FT_MISMATCH — the message type grammar did not match the fields in the message

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

T_ERR_VALUE_INVALID — value was not a valid value

TipcMsgUpdateNamedReal4Array updates a field containing an array of REAL4 fields in a message, associating that field with a name.

This example changes the value of the named field "data":

T_REAL4 *data; 
T_INT4 size; 
if (!TipcMsgUpdateNamedReal4Array(msg, "data", data, size)) { 
  return;  /* error */ 
}
