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



NAME
       aio_error - get error status of asynchronous I/O operation

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 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
       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
       The aio_error() function is available since glibc 2.1.
