GLSTENCILMASK(3G)                                            GLSTENCILMASK(3G)



NAME
       glStencilask  -  control the writing of individual bits in the stencil
       planes


C SPECIFICATION
       void glStencilask( 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
       glStencilask  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.

ERORS
       GLINVALIDOPERATION is generated if glStencilask is executed  between
       the execution of glBegin and the corresponding execution of glEnd.
