Yes and no:  the X server interprets single-touch input as pointer
events.  It is not exactly like a mouse, since a mouse is a relative
device and usually has buttons, a touch is an absolute device that does
not have buttons.

Since the interpretation of war input events is done in the X server,
you can look at the linux input source for any touchscreen for examples.
 Your best bet is to follow the type B protocol documented in the kernel
