Set page to be visible on screen.
void __fastcall__ tgi_setviewpage (unsigned char page);
If the drawpage and the viewpage are the same then all drawing is seen immediately as it is drawn. For double buffered games you can set the drawpage to a different page than the viewpage. This lets you draw the next screen in the background and when the screen is ready you display it.
- The function is only available as fastcall function, so it may only be used in presence of a prototype.
