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. The initial value 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'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.
