#include <libaio.h>

long io_submit (aio_context_t ctx_id, long nr, struct iocb **iocbpp);

io_submit() queues nr I/O request blocks for processing in the AIO context ctx_id. iocbpp should be an array of nr AIO request blocks, which will be submitted to context ctx_id.

io_submit() returns the number of iocbs submitted and 0 if nr is zero.

EINVAL	The aio_context specified by ctx_id is invalid. nr is less than 0. The iocb at *iocbpp[0] is not properly initialized, or the operation specified is invalid for the file descriptor in the iocb.
EFAULT	One of the data structures points to invalid data.
EBADF	The file descriptor specified in the first iocb is invalid.
EAGAIN	Insufficient resources are available to queue any iocbs.
ENOSYS	io_submit() is not implemented on this architecture.

io_submit() is Linux specific and should not be used in programs that are intended to be portable.

The asynchronous I/O system calls first appeared in Linux 2.5, August 2002.

io_setup(2), io_destroy(2), io_getevents(2), io_cancel(2).

The asynchronous I/O system calls were written by Benjamin LaHaise.
