LIBRARY
OpenGLUT - window
SYNOPSIS
In openglut.h
Ft void*
Fn glutGetWindowData void
DESCRIPTION
This function will return whatever
Bf Sy
void*
Ef
value is
associated with the
Bf Li
current window
Ef
via glutSetWindowData().
This is
Bf Sy
NULL
Ef
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
Bf Em
could
Ef
keep track of the
Bf Li
window id
Ef
s in a
global list and search for the
Bf Li
current window
Ef
in
that list. But this is quicker than searching a data
structure, and allows you to avoid the use of globals for this.
