AIO_ERROR(3)              Linux Programmer's Manual             AIO_ERROR(3)

NAME         top

       aio_error - get error status of asynchronous I/O operation

SYNOPSIS         top

       #include <aio.h>

       int aio_error(const struct aiocb *aiocbp);

       Link with -lrt.

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.

       *  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.

VERSIONS         top

       The aio_error() function is available since glibc 2.1.

CONFORMING TO         top

       POSIX.1-2001, POSIX.1-2008.

EXAMPLE         top

       See aio(7).
