C SPECIFICATION

void ggllIInnddeexxddvv( const GLdouble _*_c )

void ggllIInnddeexxffvv(
const GLfloat _*_c )

const GLint _*_c )


void ggllIInnddeexxssvv(
const GLshort _*_c )


void ggllIInnddeexxuubbvv(
const GLubyte *c);  _1_._1 )


        

PARAMETERS

_1_._1
Specifies a pointer to a one-element array that contains the new value for the current color index.

DESCRIPTION

ggllIInnddeexx updates the current (single-valued) color index. It takes one argument, the new value for the current color index.

The current index is stored as a floating-point value. Integer values are converted directly to floating-point values, with no special mapping. The initial value is 1.

Index values outside the representable range of the color index buffer are not clamped. However, before an index is dithered (if enabled) and written to the frame buffer, it is converted to fixed-point . Any bits in the integer portion of the resulting fixed-point value that do not correspond to bits in the frame buffer are masked out.

NOTES

ggllIInnddeexxuubb and ggllIInnddeexxuubbvv are available only if the GL version is 1.1 or greater.

The current index can be updated at any time. In particular, ggllIInnddeexx can be called between a call to ggllBBeeggiinn and the corresponding call to ggllEEnndd.
