NAME

6       glClearIndex - specify the clear value for the color index buffers
7

C SPECIFICATION

9       void glClearIndex(GLfloat c);
10

PARAMETERS

12       c
13           Specifies the index used when the color index buffers are cleared.
14           The initial value is 0.
15

DESCRIPTION

17       glClearIndex specifies the index used by glClear() to clear the color
18       index buffers.  c is not clamped. Rather, c is converted to a
19       fixed-point value with unspecified precision to the right of the binary
20       point. The integer part of this value is then masked with 2 m - 1,
21       where m is the number of bits in a color index stored in the frame
22       buffer.
23

ERRORS

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