); |

Parameters
mask
A bit mask to
enable and disable writing of individual bits in the stencil planes. Initially,
the mask is all ones.
Remarks
The glStencilMask
function 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.
