glStencilMask(3G)              OpenGL Reference              glStencilMask(3G)



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 stencil
     buffer.  Where a 0 appears, the corresponding bit is write-protected.
     Initially, all bits are enabled for writing.

ERRORS
     GLINVALIDOPERATION is generated if glStencilMask is executed between
     the execution of glBegin and the corresponding execution of glEnd.

ASSOCIATED GETS
     glGet with argument GLSTENCILWRITEMASK
     glGet with argument GLSTENCILBITS
