searching for xlib and tcp mostly brings up info about ssh to remote x server or similar. Am not finding any info about how to program sockets inside an opengl and xlib program. Maybe I ought to read the xlib manual. Would I just copy the u_pdsend and u_pdrecieve functions inside my code? Or is there tcp sockets built in to the event handling? Am wanting to use the nifty rapid graphical programming environment to add some tcl/tk controls to my opengl xlib mandelbox renderer because it is currently a challenge to translate my old gui controls to work with the xwindows event processing. The eventual goal is to add the zoom function and navigation in 3d for my sequencer in pd. But first I just want to sync the pd mandelbox sequencer with the opengl xlib visualization( so the current point that is getting sequenced in pd shows up graphically by hilighting the point within the voxelspace as well as plotting the orbits).
