aio_error(3)            Library Functions Manual            aio_error(3)

NAME         top

       aio_error - get error status of asynchronous I/O operation

LIBRARY         top

       Real-time library (librt, -lrt)

SYNOPSIS         top

       #include <aio.h>

       int aio_error(const struct aiocb *aiocbp);

DESCRIPTION         top

       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.)

RETURN VALUE         top

       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.

       > 0    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.

ERRORS         top

       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.
