aio_error - get error status of asynchronous I/O operation

  #include <aio.h>

  int aio_error(const struct aiocb *aiocbp);

  Link with -lrt.

The *aio_error*() function returns the error status for the asynchronous I/O request with control block pointed to by aiocbp. (See *aio*(7) for a description of the aiocb structure.)

This function returns one of the following:

• EINPROGRESS, if the request has not been completed yet.
• ECANCELED, if the request was canceled.
• 0, if the request completed successfully.
• A positive error number, if the asynchronous I/O operation failed. This is the same value that would have been stored in the errno variable in the case of a synchronous *read*(2), *write*(2), *fsync*(2), or *fdatasync*(2) call.

EINVAL

aiocbp does not point at a control block for an asynchronous I/O request of which the return status (see *aio_return*(3)) has not been retrieved yet.

ENOSYS

*aio_error*() is not implemented.
