IO_CANCEL(2) Linux Programmer’s Manual IO_CANCEL(2)
NAME
io_cancel - cancel an outstanding asynchronous I/O operation
SYNOPSIS
#include <libaio.h>
int io_cancel(aio_context_t ctx_id, struct iocb *iocb,
struct io_event *result);
Link with -laio.
This doesn't compile though:
$ gcc -c test_iocancel.c
test_iocancel.c: In function ‘main’:
test_iocancel.c:5: error: ‘aio_context_t’ undeclared (first use in this
function)
test_iocancel.c:5: error: (Each undeclared identifier is reported only once
test_iocancel.c:5: error: for each function it appears in.)
test_iocancel.c:5: error: expected ‘;’ before ‘ctx’
test_iocancel.c:9: error: ‘ctx’ undeclared (first use in this function)
$ cat test_iocancel.c
#include <libaio.h>
int
main(void)
{
aio_context_t ctx;
struct iocb cb;
struct io_event res;return io_cancel(ctx, &cb, &res); } $ grep -r aio_context_t /usr/include/ /usr/include/linux/aio_abi.h:typedef unsigned long aio_context_t; $
The manpages are based off of Fedora 13, as is the image that I'm currently running in VMware fusion.

Resolution| |OBSOLETE--- Comment #1 from Michael Kerrisk <[email protected]> 2012-08-16 06:25:44 --- There have been various recent changes to the io_* man pages which I think
probably address this report. If, after checking the latest version of the
pages, you believe otherwise, please re-open. Closing for now.
