There are several system modules included in DirectFB (systems directory). For a really simple one check out the devmem system. Basically the system module needs to implement the functions in CoreSystemFuncs (see src/core/core_system.h and src/core/system.h). > Can you define "primary layer"? Well you need at least one layer to do anything. That would be the primary layer. It can be implemented in the system module (most existing system modules do this) or it could be left for the gfxdriver to implement (devmem system does not implement a primary layer). Additional layers could be implement in the system module and/or gfxdrivers. > Any pointers on where to look in the API documents, or tutorials, or anything > for how to go about this will help.

Start with the devmem module, then you could check out the sdl system which adds the primary layer. Ask if you have further questions. -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ _______________________________________________ directfb-dev mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
