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