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

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

NAME

       glStencilMask - control the 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 sten-
       cil 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
