AIO_ERROR(2)		    BSD	System Calls Manual		  AIO_ERROR(2)

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

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()
     returns 0.	 If the	request	has not	yet completed, EINPROGRESS is re-
     turned.  If the request has completed unsuccessfully the error status is
     returned as described in read(2), write(2), or fsync(2).  On failure,
     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.
