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
