DUMB_FRAME_BUFFER(3GC) AVIATOR GRAPHICS INTERFACE CLASSES DUMB_FRAME_BUFFER(3GC)



NAME
        FB_CLASS__DUMB_FRAME_BUFFER_8BIT_INDEXED - dumb frame buffer class

SYNOPSIS
        #include <agi.h>
        register Fbuffer fbp;

        fbstart(fbp, FB_CLASS__DUMB_FRAME_BUFFER_8BIT_INDEXED)  {
        }  fbend(fbp);

DESCRIPTION
        The class FB_CLASS__DUMB_FRAME_BUFFER_8BIT_INDEXED is used for
        accessing the 8 bit indexed dumb (non-accelerated) frame buffer
        directly.  The pointers to the buffers are not guaranteed to be
        correct outside the compound-statement fbstart(3G)/fbend(3G).

        The user is responsible for not rendering anything outside the
        current clip list.

MEMBERS
        The following public members can be accessed by using the routine
        fbget(3G):

        FB_MEMBER__VISIBLE__CADDR
                VISIBLE is a character pointer to the dumb frame which is
                currently visible.
        FB_MEMBER__HIDDEN__CADDR
                HIDDEN is a character pointer to the dumb frame which is
                currently not visible.  HIDDEN returns 0 if double buffering
                is not available or is disabled by at least one window.
