ASTATUS(2-SVR3)     RISC/os Reference Manual      ASTATUS(2-SVR3)



NAME
     astatus - get asynchronous I/O completion status

SYNOPSIS
     #include <sys/aio.h>

     int astatus(aiohandlet handle, struct aiocb *aiocb);


DESCRIPTION
     astatus returns the completion status block for the asyn-
     chronous I/O operation associated with the handle argument.

     The aiocb argument is a pointer to an asynchronous I/O com-
     pletion block.

RETURNS
     astatus returns EINPROGRESS if the requested I/O is in pro-
     gress; otherwise it returns errno, which is also stored
     inside the completion block.

ERRORS
     If any of the following conditions occur, astatus returns -1
     and sets errno to the corresponding value:

     [EINVAL]       The handle argument is not a valid asynchro-
                    nous I/O handle.

     [EFAULT]       The aiocb handle points to a piece of unac-
                    cessible memory.
