GLCLEARINDEX(3G)                                              GLCLEARINDEX(3G)



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 2m-1, where
       m is the number of bits in a color index stored in the frame buffer.

ERORS
       GLINVALIDOPERATION is generated if glClearIndex is  executed  between
       the execution of glBegin and the corresponding execution of glEnd.

ASOCIATED GETS
       glGet with argument GLINDEXCLEARVALUE
       glGet with argument GLINDEXBITS
