NAME
       aio_error - Returns the error status of a specified asynchronous I/O operation (P1003.1b)

LIBRARY
       Asynchronous I/O Library (libaio, libaio_raw)

SYNOPSIS
       #include <aio.h>

       int aio_error (const struct
       aiocb *aiocbp);

PARAMETERS
       *aiocbp	   A pointer to the address of the aiocb structure.

DESCRIPTION
       The aio_error function returns the error status associated with the aiocb structure referenced by the aiocbp argument.  The error status is
       the errno value that is set by the corresponding asynchronous I/O read, write, or fsync operation.

       The aio_error function returns EINPROGRESS until the asynchronous I/O operation is complete. When  the  operation  is  complete,  call  the
       aio_return function to determine if the operation was successful.

RETURN VALUES
       If the asynchronous I/O operation was successful, a value of 0 is returned.

       If the asynchronous I/O operation has not yet completed, [EINPROGRESS] is returned.

       If the aio_error operation was canceled, [ECANCELED] is returned.

       On an unsuccessful call, the value returned corresponds to those error values returned for a failed read, write, or fsync operation.

ERRORS
       The aio_error function fails under the following conditions:

       [EINVAL]       The aiocbp argument does not refer to an asynchronous operation whose return status has not yet been retrieved.
