SYNOPSIS

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) is returned. 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. | |
