io_submit: Odeslat asynchronní I / O bloky ke zpracování

Originální popis anglicky: io_submit - Submit asynchronous I/O blocks for processing

Návod, kniha: Linux Programmer's Manual

STRUČNĚ

#include <linux/aio.h>

POPIS / INSTRUKCE

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.

NÁVRATOVÁ HODNOTA

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

CHYBY / ERRORY

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.

 

ODPOVÍDAJÍCÍ

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.
