glClearIndex(3G)
NAME
  glClearIndex - specify the clear value for the color index buffers

SYNOPSIS
  void glClearIndex(
	  GLfloat c );

PARAMETERS
  c   Specifies the index used when the color index buffers are cleared. The
      initial value is 0.

DESCRIPTION
  glClearIndex() specifies the index used by glClear() to clear the color
  index buffers.  c is not clamped. Rather, c is converted to a fixed-point
  value with unspecified precision to the right of the binary point. The
  integer part of this value is then masked with 2 sup m-1, where m is the
  number of bits in a color index stored in the frame buffer.

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

ASSOCIATED GETS
       glGet() with argument GL_INDEX_CLEAR_VALUE
       glGet() with argument GL_INDEX_BITS
