#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.
