`IP_QueueWrite`

IP_QueueWrite — writes a message to a queue.

Syntax

#include <cogent.h>
int IP_QueueWrite( int   qid, 
  void*   msg, 
  int   length, 
  int   priority);

Arguments

qid: A queue ID.
msg: The message buffer to be sent to the queue.
length: The length in bytes of msg.
priority: The priority of this message.

Returns

0 on success, or -1 on failure and errno is set.

Description

This function writes a message to the queue specified by qid. Higher priority numbers are treated as having a higher priority. Priority ordering is not currently implemented. A single write to the queue is limited by the operating system. Queue messages transmitted in a single write will never be broken apart or concatenated with other messages.
