`IP_QueueOpen`

IP_QueueOpen — opens a queue for reading or writing.

Syntax

#include <cogent.h>
int IP_QueueOpen( char*   name, 
  int   nid, 
  int   max_msgs, 
  int   mode);

Arguments

name: A queue name.
nid: A node ID on which to open the queue.
max_msgs: The maximum number of messages if creating the queue.
mode: The open mode for the queue.

Returns

A queue ID on success, or -1 on failure and errno is set.

Description

This function opens a queue for reading or writing, as well as possibly creating it. The max_msgs is ignored unless the queue is being created. The possible values for mode are the same as the open modes for the open system call. Typically a queue should be opened for reading or writing, but not both.
