NAME


       aio_error - get error status of asynchronous I/O operation

 

SYNOPSIS


       #include 

       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.

 

RETURN VALUE


       This function returns EINPROGRESS if the request has not been completed
       yet.   It  returns ECANCELED if the request was canceled.  It returns 0
       if the request completed successfully.  Otherwise  an  error  value  is
       returned, the same value that would have been stored in the errno vari-
       able in case of a synchronous read, write, fsync, or fdatasync request.
       On error, the error value is returned.

 

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.

 

CONFORMING TO
