(xlib) create my own properties for windowmanagers

Question

Can i create my own properties with:

XChangeProperty(display, w, property, type, format, mode, data, nelements)

or can i only use the properties shown in standards.freedesktop.org?

Answer 1

You can create any property you want.

Just do XInternAtom with your unique atom name, and you have a property of your own. Same for type.
