NAME

6       io_submit - Submit asynchronous I/O blocks for processing
7

SYNOPSIS

9       #include <libaio.h>
10
11
12       int io_submit (aio_context_t ctx_id, long nr, struct iocb **iocbpp);
13
14

DESCRIPTION

16       io_submit() queues nr I/O request blocks for processing in the AIO con‐
17       text ctx_id. iocbpp should be an array of nr AIO request blocks,  which
18       will be submitted to context ctx_id.
19
20

RETURN VALUE

22       io_submit() returns the number of iocbs submitted and 0 if nr is zero.
23
24

ERRORS

26       EINVAL The aio_context specified by ctx_id is invalid.  nr is less than
27              0. The iocb at *iocbpp[0] is not properly  initialized,  or  the
28              operation  specified  is  invalid for the file descriptor in the
29              iocb.
30
31
32       EFAULT One of the data structures points to invalid data.
33
34
35       EBADF  The file descriptor specified in the first iocb is invalid.
36
37
38       EAGAIN Insufficient resources are available to queue any iocbs.
39
40
41       ENOSYS io_submit() is not implemented on this architecture.
42
43

CONFORMING TO

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

VERSIONS

50       The  asynchronous  I/O system calls first appeared in Linux 2.5, August
51       2002.
