AIO_ERROR(2)		       System Calls Manual		    AIO_ERROR(2)

NAME
     aio_error -- retrieve error status of asynchronous I/O operation (REALTIME)

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <aio.h>

     int
     aio_error(const struct aiocb *iocb);

DESCRIPTION
     The  aio_error()  system  call returns the error status of the asynchronous
     I/O request associated with the structure pointed to by iocb.

RETURN VALUES
     If the asynchronous I/O request has completed successfully, aio_error() re-
     turns 0.  If the request has not yet completed,  EINPROGRESS  is  returned.
     If the request has completed unsuccessfully the error status is returned as
     described in read(2), readv(2), write(2), writev(2), or fsync(2).	On fail-
     ure, aio_error() returns -1 and sets errno to indicate the error condition.

ERRORS
     The aio_error() system call will fail if:

     [EINVAL]		The  iocb  argument  does  not	reference an outstanding
			asynchronous I/O request.

STANDARDS
     The  aio_error()  system call is expected to conform to the IEEE Std 1003.1
     ("POSIX.1") standard.
