IO_DESTROY
Section: Linux Programmer's Manual (2)
Updated: 2008-06-18
NAME
io_destroy - destroy an asynchronous I/O context
SYNOPSIS
#include <libaio.h>
int io_destroy(aio_context_t ctx);
Link with -laio.
DESCRIPTION
io_destroy()
removes the asynchronous I/O context from the list of
I/O contexts and then destroys it.
io_destroy()
can also cancel any outstanding asynchronous I/O
actions on ctx and block on completion.
RETURN VALUE
On success,
io_destroy()
returns 0.
For the failure return, see NOTES.
ERRORS
- EFAULT
-
The context pointed to is invalid.
- EINVAL
-
The AIO context specified by ctx is invalid.
- ENOSYS
-
io_destroy()
is not implemented on this architecture.
VERSIONS
The asynchronous I/O system calls first appeared in Linux 2.5, August 2002.
CONFORMING TO
io_destroy()
is Linux-specific and should not be used in programs
that are intended to be portable.
NOTES
Glibc does not provide a wrapper function for this system call.
The wrapper provided in
libaio
for
io_destroy()
does not follow the usual C library conventions for indicating error:
on error it returns a negated error number
(the negative of one of the values listed in ERRORS).
If the system call is invoked via
syscall(2),
then the return value follows the usual conventions for
indicating an error: -1, with
errno
set to a (positive) value that indicates the error.
