io_submit - submit asynchronous I/O blocks for processing
int io_submit(aio_context_t ctx_id, long nr, struct iocb **iocbpp);
Link with -laio.
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.
EINVAL The aio_context specified by ctx_id is invalid. nr is less than
0. The iocb at *iocbpp is not properly initialized, or the
operation specified is invalid for the file descriptor in the
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.
The asynchronous I/O system calls first appeared in Linux 2.5, August
io_submit() is Linux-specific and should not be used in programs that
are intended to be portable.
