glIndexMask(3G)
NAME
  glIndexMask - control the writing of individual bits in the color index
  buffers

SYNOPSIS
  void glIndexMask(
	  GLuint mask );

PARAMETERS
  mask
      Specifies a bit mask to enable and disable the writing of individual
      bits in the color index buffers. Initially, the mask is all 1's.

DESCRIPTION
  glIndexMask() controls the writing of individual bits in the color index
  buffers. The least significant n bits of mask, where n is the number of
  bits in a color index buffer, specify a mask. Where a 1 (one) appears in
  the mask, it's possible to write to the corresponding bit in the color
  index buffer (or buffers). Where a 0 (zero) appears, the corresponding bit
  is write-protected.

  This mask is used only in color index mode, and it affects only the buffers
  currently selected for writing (see glDrawBuffer()).	Initially, all bits
  are enabled for writing.

ERRORS
  GL_INVALID_OPERATION is generated if glIndexMask() is executed between the
  execution of glBegin() and the corresponding execution of glEnd().

ASSOCIATED GETS
  glGet() with argument GL_INDEX_WRITEMASK
