16 This function will return whatever void* value is associated with the
17 current window via glutSetWindowData(). This is NULL if you did not
18 associate a pointer with your window. This can be useful in a situation
19 where you have a single callback function performing services for many
20 windows. You could keep track of the window id s in a global list
21 and search for the current window in that list. But this is quicker
22 than searching a data structure, and allows you to avoid the use of glob‐
23 als for this.
