NAME    [Toc]    [Back]

       glClearIndex - specify the clear value for the color index
       buffers

SYNOPSIS    [Toc]    [Back]

       void glClearIndex(
               GLfloat c );

PARAMETERS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       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]    [Back]

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

ASSOCIATED GETS    [Toc]    [Back]

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