NAME

6       glStencilMask - control the front and back writing of individual bits
7       in the stencil planes
8

C SPECIFICATION

10       void glStencilMask(GLuint mask);
11

PARAMETERS

13       mask
14           Specifies a bit mask to enable and disable writing of individual
15           bits in the stencil planes. Initially, the mask is all 1's.
16

DESCRIPTION

18       glStencilMask controls the writing of individual bits in the stencil
19       planes. The least significant n bits of mask, where n is the number of
20       bits in the stencil buffer, specify a mask. Where a 1 appears in the
21       mask, it's possible to write to the corresponding bit in the stencil
22       buffer. Where a 0 appears, the corresponding bit is write-protected.
23       Initially, all bits are enabled for writing.
24
25       There can be two separate mask writemasks; one affects back-facing
26       polygons, and the other affects front-facing polygons as well as other
27       non-polygon primitives.  glStencilMask() sets both front and back
28       stencil writemasks to the same values. Use glStencilMaskSeparate() to
29       set front and back stencil writemasks to different values.
30

NOTES

32       glStencilMask() is the same as calling glStencilMaskSeparate() with
33       face set to GL_FRONT_AND_BACK.
34

ASSOCIATED GETS

36       glGet() with argument GL_STENCIL_WRITEMASK, GL_STENCIL_BACK_WRITEMASK,
37       or GL_STENCIL_BITS
