NAME

       io_destroy - destroy an asynchronous I/O context

SYNOPSIS

       #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.

DESCRIPTION

       Note:  this  page describes the raw Linux system call interface.  The wrapper function provided by libaio
       uses a different type for the ctx_id argument.  See NOTES.

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

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_id is invalid.

       ENOSYS io_destroy() is not implemented on this architecture.

VERSIONS

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

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.  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_context_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.
