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

       io_destroy - destroy an asynchronous I/O context

       #include <linux/aio_abi.h>	   /* Defines needed types */

       int io_destroy(aio_context_t ctx_id);

       Note: There is no glibc wrapper for this system call; see NOTES.

       The  io_destroy()  system  call	will attempt to cancel all outstanding
       asynchronous I/O operations against ctx_id, will block on  the  comple‐
       tion of all operations that could not be canceled, and will destroy the

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

       EFAULT The context pointed to is invalid.

       EINVAL The AIO context specified by ctx_id is invalid.

       ENOSYS io_destroy() is not implemented on this architecture.

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

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

       Glibc  does  not	 provide a wrapper function for this system call.  You
       could invoke it using syscall(2).  But instead, you  probably  want  to
       use the io_destroy() wrapper function provided by libaio.

       Note  that  the	libaio wrapper function uses a different type (io_con‐
       text_t) for the ctx_id argument.	 Note also  that  the  libaio  wrapper
       does  not follow the usual C library conventions for indicating errors:
       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.
