io_destroy(2) System Calls Manual io_destroy(2)
io_destroy - destroy an asynchronous I/O context
Standard C library (libc, -lc)
#include <linux/aio_abi.h> /* Definition of aio_context_t */
#include <sys/syscall.h> /* Definition of SYS_* constants */
#include <unistd.h>
int syscall(SYS_io_destroy, aio_context_t ctx_id);
Note: glibc provides no wrapper for io_destroy(), necessitating
the use of syscall(2).
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 VERSIONS.
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.
On success, io_destroy() returns 0. For the failure return, see
VERSIONS.
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.
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.
