NAME

glClearIndex - specify the clear value for the color index buffers

C SPECIFICATION

void ggllCClleeaarrIInnddeexx( GLfloat _c )

        

delim $$

PARAMETERS

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

DESCRIPTION

ggllCClleeaarrIInnddeexx specifies the index used by ggllCClleeaarr 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 $2 sup m^-^1$, where $m$ is the number of bits in a color index stored in the frame buffer.

ERRORS

GGLL__IINNVVAALLIIDD__OOPPEERRAATTIIOONN is generated if ggllCClleeaarrIInnddeexx is executed between the execution of ggllBBeeggiinn and the corresponding execution of ggllEEnndd.
