NAME

io_submit − Submit asynchronous I/O blocks for processing

SYNOPSIS

#include <libaio.h>

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

DESCRIPTION

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.

RETURN VALUE

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

ERRORS

	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.

CONFORMING TO

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

VERSIONS

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

SEE ALSO

NOTES

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