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

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

     Standard C Library (libc, -lc)

     #include <aio.h>

     aio_error(const struct aiocb *aiocbp);

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

     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.

     The aio_error() system call will fail if:

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

     aio_cancel(2), aio_read(2), aio_return(2), aio_suspend(2), aio_write(2), fsync(2), read(2), write(2),

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

     The aio_error() system call first appeared in FreeBSD 3.0.
