glStencilMask(3G)glStencilMask(3G)NAMEglStencilMask - control the writing of individual bits in the stencil
planes
SYNOPSIS
void glStencilMask(
GLuint mask );
PARAMETERS
Specifies a bit mask to enable and disable writing of individual bits
in the stencil planes. Initially, the mask is all 1's.
DESCRIPTIONglStencilMask() 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
GL_INVALID_OPERATION is generated if glStencilMask() is executed
between the execution of glBegin() and the corresponding execution of
glEnd().
