glStencilMask
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 called between a call to glBegin and the corresponding call to glEnd.
ASSOCIATED GETS
glGet with argument GL_STENCIL_WRITEMASK
glGet with argument GL_STENCIL_BITS
