Pushes and pops the name stack.
OpenGL C bindings library: libGL.a
void glPushName(GLuint Name)
void glPopName(void)
| Name | Specifies a name that will be pushed onto the name 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 glPushName subroutine causes the Name parameter to be pushed onto the name stack, which is initially empty. The glPopName subroutine pops one name off the top of the stack.
It is an error to push a name onto a full stack, or to pop a name off an empty stack. It is also an error to manipulate the name stack between a call to the glBegin subroutine and the corresponding call to the glEnd subroutine. In any of these cases, the error flag is set and no other change is made to GL state.
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.
Associated gets for the glPushName or glPopName subroutine are as follows. (See the glGet subroutine for more information.)
glGet with argument GL_NAME_STACK_DEPTH
glGet with argument GL_MAX_NAME_STACK_DEPTH.
