thanks for your link.
BTW i have already found and began to use SDL_net an add on library
on SDL (www.libsdl.org) wich is an excellent cross platform, simple
and low-level access to video, joystick, keyboard, mouse, thread,
sound and timer (do i forget something ?)
and completly free of charge and open source.
this edited by developper of loki games. i feel i will try their
game, i already enjoy "call to power" !
SDL is great and i can only suggest anybody to use it !!! :-)
