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.
