aio_group_completion_np(3)				     Library Functions Manual					aio_group_completion_np(3)

NAME

       aio_group_completion_np - Enables the use of aio_results_np function

LIBRARY

       Asynchronous I/O Library (libaio, libaio_raw)

SYNOPSIS

       #include <aio.h>

       int aio_group_completion_np ( void );

PARAMETERS

       None.

DESCRIPTION

       The aio_group_completion_np function enables an application to use aio group completion through the aio_result_np function.

       The  function  must  be	called	before any other aio function.	After this call, the use of the aio_error and aio_return functions becomes
       undefined, and they may return unexpected errors.  The best practice is never to intermix the two forms of  aio	completion.   Calling  the
       function after the use of any other aio function results in failure.

RETURN VALUES

       If  the	function  returns  successfully, the number of completed aio operations reported on is returned.  That is, the return value is the
       number of valid entries in the array.  If the value returned is the same as the nent argument, more aio operations may be complete and  can
       be reported on by another call to aio_results_np.

       On an unsuccessful call, a value of -1 is returned and errno is set to indicate that an error occurred.

ERRORS

       The aio_group_completion_np function fails under the following conditions:

       [EINVAL]       Another aio function has already been called.

       [EAGAIN]       Inadequate system resources exist to enable group completion at this time.
