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

C SPECIFICATION
       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 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

SEE ALSO
       glClear()
