io_queue_init3

Usage

#include <errno.h>

#include <libaio.h>

int io_queue_init(int maxevents, io_context_t *ctx);

Overview

io_queue_init() attempts to create an aio context capable of receiving at least maxevents events. ctx must point to an aio context that already exists and must be initialized to 0 before the call. If the operation is successful, *cxtp is filled with the resulting handle.

Return values

On success, io_queue_init() returns 0. Otherwise, -error is return, where error is one of the Exxx values defined in the ERRORS section.
