glStencilMask(3G)					     glStencilMask(3G)

NAME
       glStencilMask  -	 control the writing of individual bits in the stencil
       planes

SYNOPSIS
       void glStencilMask(
	       GLuint mask );

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

DESCRIPTION
       glStencilMask()	controls the writing of individual bits in the stencil
       planes. The least significant n bits of mask, 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.

ERRORS
       GL_INVALID_OPERATION  is	 generated  if	glStencilMask()	 is   executed
       between	the  execution of glBegin() and the corresponding execution of
       glEnd().

ASSOCIATED GETS
       glGet() with argument GL_STENCIL_WRITEMASK
       glGet() with argument GL_STENCIL_BITS
