SYNOPSIS [Toc]

 #include <aio.h>

 aio_error(const struct aiocb *iocb);

DESCRIPTION [Toc]

 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 [Toc]

 If the asynchronous I/O request has completed successfully, aio_error()
 returns 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), write(2), or fsync(2) is returned.
 On failure, aio_error() returns -1 and sets errno to indicate the error
 condition.

ERRORS [Toc]

 The aio_error() system call will fail if:
 [EINVAL]		The iocb argument does not reference an outstanding
			asynchronous I/O request.
