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.

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
       variable 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
       POSIX.1-2001.
