     <STRONG>NAME</STRONG>
	  <STRONG>glStencilMask</STRONG>	- control the writing of individual bits in
	  the stencil planes


     <STRONG>C</STRONG> <STRONG>SPECIFICATION</STRONG>
	  void <STRONG>glStencilMask</STRONG>( GLuint <EM>mask</EM> )


     <STRONG>PARAMETERS</STRONG>
	  <EM>mask</EM>	Specifies a bit	mask to	enable and disable writing of
		individual bits	in the stencil planes.	Initially, the
		mask is	all 1's.

     <STRONG>DESCRIPTION</STRONG>
	  <STRONG>glStencilMask</STRONG>	controls the writing of	individual bits	in the
	  stencil planes.  The least significant n bits	of <EM>mask</EM>, where
	  n is the number of bits in the stencil buffer, specify a
	  mask.	 Where a 1 appears in the mask,	it's possible to write
	  to the corresponding bit in the stencil buffer.  Where a 0
	  appears, the corresponding bit is write-protected.
	  Initially, all bits are enabled for writing.

     <STRONG>ERRORS</STRONG>
	  <STRONG>GL_INVALID_OPERATION</STRONG> is generated if <STRONG>glStencilMask</STRONG> is
	  executed between the execution of <STRONG>glBegin</STRONG> and	the
	  corresponding	execution of <STRONG>glEnd</STRONG>.

     <STRONG>ASSOCIATED</STRONG>	<STRONG>GETS</STRONG>
	  <STRONG>glGet</STRONG>	with argument <STRONG>GL_STENCIL_WRITEMASK</STRONG>
	  <STRONG>glGet</STRONG>	with argument <STRONG>GL_STENCIL_BITS</STRONG>
