It	  consists of an ordered set of	unsigned integers and is	  initially empty.	  <STRONG>glPushName</STRONG> causes <EM>name</EM> to be pushed onto the name stack.	  <STRONG>glPopName</STRONG> pops one name off the top of the stack.	  The maximum name stack depth is implementation-dependent;	  call <STRONG>GL_MAX_NAME_STACK_DEPTH</STRONG> 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 <STRONG>glBegin</STRONG> and the corresponding execution of	  <STRONG>glEnd</STRONG>.  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	  <STRONG>GL_SELECT</STRONG>.  Calls to <STRONG>glPushName</STRONG> or <STRONG>glPopName</STRONG> while the	  render mode is not <STRONG>GL_SELECT</STRONG> are ignored.     <STRONG>ERRORS</STRONG>	  <STRONG>GL_STACK_OVERFLOW</STRONG> is generated if <STRONG>glPushName</STRONG> is called while	  the name stack is full.	  <STRONG>GL_STACK_UNDERFLOW</STRONG> is	generated if <STRONG>glPopName</STRONG> is called while	  the name stack is empty.	  <STRONG>GL_INVALID_OPERATION</STRONG> is generated if <STRONG>glPushName</STRONG> or <STRONG>glPopName</STRONG>	  is executed between a	call to	<STRONG>glBegin</STRONG>	and the	corresponding	  call to <STRONG>glEnd</STRONG>.     <STRONG>ASSOCIATED</STRONG>	<STRONG>GETS</STRONG>	  <STRONG>glGet</STRONG>	with argument <STRONG>GL_NAME_STACK_DEPTH</STRONG>	  <STRONG>glGet</STRONG>	with argument <STRONG>GL_MAX_NAME_STACK_DEPTH</STRONG>     <STRONG>SEE</STRONG> <STRONG>ALSO</STRONG>	  <STRONG>glInitNames</STRONG>, <STRONG>glLoadName</STRONG>, <STRONG>glRenderMode</STRONG>, <STRONG>glSelectBuffer</STRONG></PRE></BODY></HTML>
