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
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
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_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.
