glClearIndex(3G)               OpenGL Reference               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
                                                     m
     integer part of this value is then masked with 2 -1, where m is the
     number of bits in a color index stored in the frame buffer.

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

ASSOCIATED GETS
     glGet with argument GLINDEXCLEARVALUE
     glGet with argument GLINDEXBITS
