void glStencilMask( GLuint mask )

mask	Specifies a bit mask to enable and disable writing of individual bits in the stencil planes. Initially, the mask is all 1’s.

 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.

 GL_INVALID_OPERATION is generated if  glStencilMask is executed between the execution of  glBegin and the corresponding execution of  glEnd.
