GLCLEARINDEX()							GLCLEARINDEX()

NAME
       glClearIndex - specify the clear	value for the color index buffers

C SPECIFICATION
       void glClearIndex( GLfloat c )

       delim $$

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 in-
       dex  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
