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
