NAME

io_destroy - destroy an asynchronous I/O context  

LIBRARY

Standard C library (libc,~-lc)  

SYNOPSIS

#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);

 

DESCRIPTION

Note: you probably want to use the io_destroy(3) wrapper function provided by libaio; 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.  

RETURN VALUE

On success, io_destroy() returns 0. On error, -1 is returned, and errno is set to indicate the error.  

ERRORS

EFAULT

ctx_id was not a valid address.

EINVAL

The AIO context specified by ctx_id is invalid.

ENOSYS

io_destroy() is not implemented on this architecture.

 

VERSIONS

libaio provides a wrapper function with the same name, but different prototype and return value. You probably want to use that wrapper.  

STANDARDS

Linux.  

HISTORY

Linux 2.5.
