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.
io_submit() is Linux
specific and should not be used in programs that are intended
to be portable.
io_setup(2), io_destroy(2), io_getevents(2), io_cancel(2).
