NAME [Toc]

 glClearIndex - specify the clear value for the color index
 buffers

SYNOPSIS [Toc]

 void glClearIndex(
 GLfloat c );

PARAMETERS [Toc]

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

DESCRIPTION [Toc]

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

ERRORS [Toc]

 GL_INVALID_OPERATION is generated if glClearIndex() is
 executed between the execution of glBegin() and the corresponding
 execution of glEnd().

ASSOCIATED GETS [Toc]

 glGet() with argument GL_INDEX_CLEAR_VALUE
 glGet() with argument GL_INDEX_BITS
