IO_DESTROY(2)              Linux Programmer's Manual             IO_DESTROY(2)

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  out-
       standing 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.
