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() 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).  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.
