Advertisements
NAME
io_submit - Submit asynchronous I/O blocks for processing
SYNOPSIS
#include <libaio.h>
Tag | Description |
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
Tag | Description |
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.
