C SPECIFICATION

       void GLAPIENTRY 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 2m-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.
