aio_error(3)                                          Library Functions Manual                                         aio_error(3)

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

LIBRARY
       Real-time library (librt, -lrt)

SYNOPSIS
       #include <aio.h>

       int aio_error(const struct aiocb *aiocbp);

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.

       > 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
       EINVAL aiocbp  does  not  point  at  a control block for an asynchronous I/O request of which the return status (see aio_re‐
              turn(3)) has not been retrieved yet.

       ENOSYS aio_error() is not implemented.

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