hi there,

i need to write a front-end GUI application (c++) for my console app, but it must be platform independent (it have to run on *nix and Win) and i am not sure what kind of interprocess communication to use (signals, fifos, sockets, semaphores). could you help me? (it is a week i found out there is something like "fifo" or "socket", so please dont use any special terms)

thanks in advance

For platform independent communication, you have to use sockets for the best results. Try this first --> http://www.ecst.csuchico.edu/~beej/guide/net/

For advanced info on interprocesses in linux, you can check this out --> http://www.advancedlinuxprogramming.com/

And if you have any doubts, post here ...

If you have library for the gui there's maybe some class available for Socket (I'm thinking about QT or wxWindow) that can simplify you a lot the programming of socket (even if socket is normaly almost plateform indenpendant).

The main problem with socket in platform indenpendant programming is that you usually need thread and this is not platform indenpendant.

If you want a library you can take a look at OpenTop for socket and thread (GPL)
OpenTop
or at boost
Boost library

Both are cross-platform


You can also use STDIN and STDOUT (or STDERR) but this is annoying if you have an only console mode.

Hope this help
