NAME    [Toc]    [Back]

     glStencilMask - control the writing of individual bits in the stencil
     planes

C SPECIFICATION    [Toc]    [Back]

     void glStencilMask( GLuint	mask )

PARAMETERS    [Toc]    [Back]

     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    [Toc]    [Back]

     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    [Toc]    [Back]

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

ASSOCIATED GETS    [Toc]    [Back]

     glGet with	argument GL_STENCIL_WRITEMASK
     glGet with	argument GL_STENCIL_BITS
