NAME

6       io_destroy - destroy an asynchronous I/O context
7

SYNOPSIS

9       #include <libaio.h>
10
11       int io_destroy(aio_context_t ctx);
12
13       Link with -laio.
14

DESCRIPTION

16       io_destroy()  removes the asynchronous I/O context from the list of I/O
17       contexts and then destroys it.  io_destroy() can also cancel  any  out‐
18       standing asynchronous I/O actions on ctx and block on completion.
19

RETURN VALUE

21       On success, io_destroy() returns 0.  For the failure return, see NOTES.
22

ERRORS

24       EFAULT The context pointed to is invalid.
25
26       EINVAL The AIO context specified by ctx is invalid.
27
28       ENOSYS io_destroy() is not implemented on this architecture.
29

VERSIONS

31       The  asynchronous  I/O system calls first appeared in Linux 2.5, August
32       2002.
33

CONFORMING TO

35       io_destroy() is Linux-specific and should not be used in programs  that
36       are intended to be portable.
37

NOTES

39       Glibc does not provide a wrapper function for this system call.
40
41       The  wrapper  provided  in  libaio for io_destroy() does not follow the
42       usual C library conventions for indicating error: on error it returns a
43       negated  error  number  (the  negative  of  one of the values listed in
44       ERRORS).  If the system call is invoked via syscall(2), then the return
45       value  follows  the usual conventions for indicating an error: -1, with
46       errno set to a (positive) value that indicates the error.
