glPopName(3G)
NAME
  glPopName, glPushName - push and pop the name stack

SYNOPSIS
  void glPopName(
	  void );

PARAMETERS
  name
      Specifies a name that will be pushed onto the name stack.

DESCRIPTION
  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 and is initially empty.

  glPushName() causes name to be pushed onto the name stack.  glPopName()
  pops one name off the top of the stack.

  The maximum name stack depth is implementation-dependent; call
  GL_MAX_NAME_STACK_DEPTH to find out the value for a particular
  implementation.  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 the execution of glBegin() and the corresponding execution of
  glEnd(). In any of these cases, the error option 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.

ERRORS
  GL_STACK_OVERFLOW is generated if glPushName() is called while the name
  stack is full.

  GL_STACK_UNDERFLOW is generated if glPopName() is called while the name
  stack is empty.

  GL_INVALID_OPERATION is generated if glPushName() or glPopName() is
  executed between a call to glBegin() and the corresponding call to glEnd().

ASSOCIATED GETS
       glGet() with argument GL_NAME_STACK_DEPTH
       glGet() with argument GL_MAX_NAME_STACK_DEPTH
