The glPushName function causes name to be pushed onto the name stack, which is initially empty. The glPopName function pops one name off the top of the stack. The name stack is used during selection mode to allow sets of rendering commands to be uniquely identified. It consists of an ordered set of unsigned integers.
The name stack is always empty while the render mode is not GL_SELECT. Calls to glPushName or glPopName while the render mode is not GL_SELECT are ignored.
The following functions retrieve information related to glPushName and glPopName:
glGet with argument GL_NAME_STACK_DEPTH
glGet with argument GL_MAX_NAME_STACK_DEPTH
