NAME
       aio_return - get return status of asynchronous I/O operation

SYNOPSIS
       #include <aio.h>

       ssize_t aio_return(struct aiocb *aiocbp);

       Link with -lrt.

DESCRIPTION
       The aio_return() function returns the final return status for the asynchronous I/O request with control block pointed to by aiocbp.

       This function should be called only once for any given request, after aio_error(3) returns something other than EINPROGRESS.

RETURN VALUE
       If  the	asynchronous  I/O  operation has completed, this function returns the value that would have been returned in case of a synchronous
       read, write, or fsync request.  Otherwise the return value is undefined.  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 has not been retrieved yet.

CONFORMING TO
       POSIX.1-2001.
