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 ones.

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.  Wherever a one appears in
     the mask, the corresponding bit in	the stencil buffer is made writable.
     Where a zero appears, the 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
