AIO_CANCEL(3)           NetBSD Library Functions Manual          AIO_CANCEL(3)

NAME
     aio_cancel -- cancel an outstanding asynchronous I/O operation (REALTIME)

LIBRARY
     POSIX Real-time Library (librt, -lrt)

SYNOPSIS
     #include <aio.h>

     int
     aio_cancel(int fildes, struct aiocb * aiocbp);

DESCRIPTION
     The aio_cancel() system call cancels the outstanding asynchronous I/O
     request for the file descriptor specified in fildes.  If aiocbp is speci-
     fied, only that specific asynchronous I/O request is cancelled.

     Normal asynchronous notification occurs for cancelled requests.  Requests
     complete with an error result of ECANCELED.

RETURN VALUES
     The aio_cancel() system call returns -1 to indicate an error, or one of
     the following:

     [AIO_CANCELED]     All outstanding requests meeting the criteria speci-
                        fied were cancelled.

     [AIO_NOTCANCELED]  Some requests were not cancelled, status for the
                        requests should be checked with aio_error(3).

     [AIO_ALLDONE]      All of the requests meeting the criteria have fin-
                        ished.

ERRORS
     An error return from aio_cancel() indicates:

     [EBADF]            The fildes argument is an invalid file descriptor.

STANDARDS
     The aio_cancel() system call is expected to conform to the IEEE Std
     1003.1-2001 (``POSIX.1'') standard.
