glStencilMask.3gl

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	executed between the
  execution of glBegin and the corresponding execution of glEnd.

Associated Gets

  glGet	with argument GL_STENCIL_WRITEMASK
  glGet	with argument GL_STENCIL_BITS
