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.
