GLSTENCILMASK(3G)						  [FIXME: manual]						 GLSTENCILMASK(3G)

NAME

       glStencilMask - control the front and back writing of individual bits in the stencil planes

C SPECIFICATION

       void glStencilMask(GLuint mask);

PARAMETERS

       mask
	   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.

       There can be two separate mask writemasks; one affects back-facing polygons, and the other affects front-facing polygons as well as other
       non-polygon primitives.	glStencilMask() sets both front and back stencil writemasks to the same values. Use glStencilMaskSeparate() to set
       front and back stencil writemasks to different values.

NOTES

       glStencilMask() is the same as calling glStencilMaskSeparate() with face set to GL_FRONT_AND_BACK.

ASSOCIATED GETS

       glGet() with argument GL_STENCIL_WRITEMASK, GL_STENCIL_BACK_WRITEMASK, or GL_STENCIL_BITS
