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

NAME         top

       io_destroy - destroy an asynchronous I/O context

SYNOPSIS         top

       #include <libaio.h>

       int io_destroy(aio_context_t ctx);

       Link with -laio.

DESCRIPTION         top

       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         top

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

ERRORS         top

       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         top

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

CONFORMING TO         top

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

NOTES         top

       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.
