vsync(3alleg4) Allegro manual vsync(3alleg4)NAME
vsync - Waits for a vertical retrace to begin. Allegro game programming library.
Waits for a vertical retrace to begin. The retrace happens when the electron beam in your monitor has reached the bottom of the screen and
is moving back to the top ready for another scan. During this short period the graphics card isn't sending any data to the monitor, so you
can do things to it that aren't possible at other times, such as altering the palette without causing flickering (snow). Allegro will auto-
matically wait for a retrace before altering the palette or doing any hardware scrolling, though, so you don't normally need to bother with

scroll_screen(3alleg4) Allegro manual scroll_screen(3alleg4)NAME
scroll_screen - Requests a hardware scroll request. Allegro game programming library.
int scroll_screen(int x, int y);
Attempts to scroll the hardware screen to display a different part of the virtual screen (initially it will be positioned at 0, 0, which is
the top left corner). You can use this to move the screen display around in a large virtual screen space, or to page flip back and forth
between two non-overlapping areas of the virtual screen. Note that to draw outside the original position in the screen bitmap you will have
to alter the clipping rectangle with set_clip_rect().
Mode-X scrolling is reliable and will work on any card, other drivers may not work or not work reliably. See the platform-specific section
of the docs for more information.
Allegro will handle any necessary vertical retrace synchronisation when scrolling the screen, so you don't need to call vsync() before it.
This means that scroll_screen() has the same time delay effects as vsync().
Returns zero on success. Returns non-zero if the graphics driver can't handle hardware scrolling or the virtual screen is not large enough.
