It will timeout if write of some page blocks for SO_SNDTIMEO.
If transmission of any page never takes more than SO_SNDTIMEO it never
times out.
You can think about sendfile() as subroutine doing:
for (;;) {
read(4K from fdin);
write(4K to fdout);
}
All the options apply to each read()/write() separetely, so that... alas.
