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.
