io_submit (2)
IO_SUBMIT(2) Linux Programmer's Manual IO_SUBMIT(2)
NAME
io_submit - submit asynchronous I/O blocks for processing
SYNOPSIS
#include <libaio.h>
int io_submit(aio_context_t ctx_id, long nr, struct iocb **iocbpp);
Link with -laio.
DESCRIPTION
io_submit() queues nr I/O request blocks for processing in the AIO con-
text ctx_id. iocbpp should be an array of nr AIO request blocks, which
will be submitted to context ctx_id.
RETURN VALUE
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.
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.
VERSIONS
The asynchronous I/O system calls first appeared in Linux 2.5, August
2002.
CONFORMING TO
io_submit() is Linux specific and should not be used in programs that
are intended to be portable.
