    So it is not possible to call my brigde functions
from the clients ? Can you explain why ?

    because my server process cannot exist in multiple
instances, as in fact it is a process using OpenGl to
draw things..

    I seek a way to call function to my server without
pipes, messages queues or sockets.

    The best solution so far would be a shared mem variable
that would be scrutinized by my main loop in server. but I
wanted to avoid this sort of round robbin with much syscalls
for the mutex handling.
