aio_error


SYNOPSIS
       #include <aio.h>

       int aio_error(const struct aiocb *aiocbp);

       Link with -lrt.

DESCRIPTION
       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
       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, 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 fdata-
          sync(2) call.

ERRORS
       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.

VERSIONS
       The aio_error() function is available since glibc 2.1.
