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 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.
ERRORS
GL_INVALID_OPERATION is generated if glClearIndex is executed between
the execution of glBegin and the corresponding execution of glEnd.
ASSOCIATED GETS
glGet with argument GL_INDEX_CLEAR_VALUE
glGet with argument GL_INDEX_BITS
