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
specified, 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 specified 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 finished.
ERRORS
An error return from aio_cancel() indicates:
[EBADF] The fildes argument is an invalid file descriptor.
SEE ALSO
aio(3)
STANDARDS
The aio_cancel() system call is expected to conform to the IEEE Std 1003.1-2001 (``POSIX.1'') standard.
HISTORY
The aio_cancel() system call first appeared in NetBSD 5.0.
