[Up] C Specification

void glClearIndex(
    GLfloat	 c)

[Up] Parameters

Specifies the index used when the color index buffers are cleared. The initial value is 0.

[Up] 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.
