IO_SUBMIT(2) Linux Programmer's Manual IO_SUBMIT(2)

io_submit - submit asynchronous I/O blocks for processing

#include <linux/aio.h>

int 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.

On success, io_submit() returns the number of iocbs submitted (which may be 0 if nr is zero); on failure, it returns one of the errors listed under ERRORS.

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.
One of the data structures points to invalid data.
The file descriptor specified in the first iocb is invalid.
Insufficient resources are available to queue any iocbs.
io_submit() is not implemented on this architecture.

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

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