I've had a little trouble understanding you... :-)
Here's an excerpt from the man page, though... if this isn't what you were
looking for, please clarify a bit...
--snip--
In the non-threaded library getsockopt() is implemented as the
getsockopt syscall.
In the threaded library, the getsockopt syscall is assembled to _thread_sys_getsockopt()
and getsockopt() is implemented as a function which locks s for read and
write, then calls _thread_sys_getsockopt().
Before returning, getsockopt() unlocks s.
--snip--
Regards,
Bosko.
