UNTITLED LOCAL UNTITLED NAME glutGetWindowData — Get the user data for the current window LIBRARY OpenGLUT - window SYNOPSIS #include <openglut.h> void* glutGetWindowData(void); DESCRIPTION This function will return whatever void* value is associated with the current window via glutSetWindowData(). This is NULL if you did not associate a pointer with your window. This can be useful in a situation where you have a single callback function performing services for many windows. You could keep track of the window id s in a global list and search for the current window in that list. But this is quicker than searching a data structure, and allows you to avoid the use of glob‐ als for this. SEE ALSO glutSetWindowData(3) Epoch[top]
