io_destroy - destroy an asynchronous I/O context
#include <linux/aio_abi.h> /* Defines needed types */
int io_destroy(aio_context_t ctx_id);
: There is no glibc wrapper for this system call; see NOTES.
() 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
On success, io_destroy

- The context pointed to is invalid.
- The AIO context specified by ctx_id is invalid.
- io_destroy() is not implemented on this architecture.
The asynchronous I/O system calls first appeared in Linux 2.5.
() 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
() wrapper function provided by libaio
Note that the libaio
wrapper function uses a different type
) for the ctx_id
argument. Note also that the
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
(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.
