Why not login as devuser in the first place, instead of ssh-ing into the wrong user? Then you'd be logged in as the right user with the right password and not have to deal with any cramming-a-bruteforced-password-into-su nonsense -- which is even more difficult than it sounds, because a UNIX password prompt is designed to prevent passwords being typed into it automatically. 'interactive password authentication' means 'password typed by a human being in realtime' authentication and no program pretending to be a human is acceptable...

iob_new
iob_new(3) Library Functions Manual iob_new(3)
NAME
iob_new - create new I/O batch
SYNTAX
#include <iob.h>
io_batch* iob_new(int hint_entries);
DESCRIPTION
iob_new creates a new I/O batch with enough space allocated for hint_entries entries (buffers or files). This is purely a performance
hint, if you are unsure just pass 1.
You can add buffers, strings and files to an I/O batch and then send it all at once using iob_send.
The benefit of the I/O batch API is that it exploits platform specific APIs like FreeBSD's sendfile. The file contents will always be sent
in a way that allows the operating systems to perform zero copy TCP, and the buffers will always be sent using as few syscalls as possible
and avoiding unnecessary copying (using writev).
RETURN VALUE
iob_new returns a pointer to an I/O batch data structure. If there was a memory allocation error, it returns NULL instead.
