NAME

6       io_destroy - destroy an asynchronous I/O context
7

SYNOPSIS

9       #include <linux/aio_abi.h>          /* Defines needed types */
10
11       int io_destroy(aio_context_t ctx_id);
12
13       Note: There is no glibc wrapper for this system call; see NOTES.
14

DESCRIPTION

16       Note:  this  page  describes  the raw Linux system call interface.  The
17       wrapper function provided by libaio  uses  a  different  type  for  the
18       ctx_id argument.  See NOTES.
19
20       The  io_destroy()  system  call  will attempt to cancel all outstanding
21       asynchronous I/O operations against ctx_id, will block on  the  comple‐
22       tion of all operations that could not be canceled, and will destroy the
23       ctx_id.
24

RETURN VALUE

26       On success, io_destroy() returns 0.  For the failure return, see NOTES.
27

ERRORS

29       EFAULT The context pointed to is invalid.
30
31       EINVAL The AIO context specified by ctx_id is invalid.
32
33       ENOSYS io_destroy() is not implemented on this architecture.
34

VERSIONS

36       The asynchronous I/O system calls first appeared in Linux 2.5.
37

CONFORMING TO

39       io_destroy() is Linux-specific and should not be used in programs  that
40       are intended to be portable.
41

NOTES

43       Glibc  does  not  provide a wrapper function for this system call.  You
44       could invoke it using syscall(2).  But instead, you  probably  want  to
45       use the io_destroy() wrapper function provided by libaio.
46
47       Note  that  the  libaio wrapper function uses a different type (io_con‐
48       text_t) for the ctx_id argument.  Note also  that  the  libaio  wrapper
49       does  not follow the usual C library conventions for indicating errors:
50       on error it returns a negated error number (the negative of one of  the
51       values   listed  in  ERRORS).   If  the  system  call  is  invoked  via
52       syscall(2), then the return value follows the usual conventions for in‐
53       dicating  an error: -1, with errno set to a (positive) value that indi‐
54       cates the error.
