GLSTENCILMASK(3G)														 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 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
