NAME

       glStencilMaskSeparate - control the front and/or back writing of individual bits in the
       stencil planes

C SPECIFICATION

       void glStencilMaskSeparate(GLenum face, GLuint mask);

PARAMETERS

       face
           Specifies whether the front and/or back stencil writemask is updated. Three symbolic
           constants are valid: GL_FRONT, GL_BACK, and GL_FRONT_AND_BACK.

       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

       glStencilMaskSeparate 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, as if
       glStencilMaskSeparate() were called with face set to GL_FRONT_AND_BACK.

ERRORS

       GL_INVALID_ENUM is generated if face is not one of the accepted tokens.

ASSOCIATED GETS

       glGet() with argument GL_STENCIL_WRITEMASK, GL_STENCIL_BACK_WRITEMASK, or GL_STENCIL_BITS
