GLSTENCILMASK(3G) UNIX Programmer's Manual GLSTENCILMASK(3G)
glStencilMask - control the writing of individual bits in
the stencil planes
void glStencilMask( GLuint mask )
mask Specifies a bit mask to enable and disable writing of
individual bits in the stencil planes. Initially, the
mask is all 1's.
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. Ini-
tially, all bits are enabled for writing.
GL_INVALID_OPERATION is generated if glStencilMask is exe-
cuted between the execution of glBegin and the corresponding
execution of glEnd.
