request_scroll(3alleg4)                                           Allegro manual                                           request_scroll(3alleg4)

NAME
request_scroll - Queues a hardware scroll request with triple buffering. Allegro game programming library. SYNOPSIS
#include <allegro.h> int request_scroll(int x, int y); DESCRIPTION
This function is used for triple buffering. It requests a hardware scroll to the specified position, but returns immediately rather than waiting for a retrace. The scroll will then take place during the next vertical retrace, but you can carry on running other code in the meantime and use the poll_scroll() routine to detect when the flip has actually taken place. Triple buffering is only possible with certain drivers: you can look at the GFX_CAN_TRIPLE_BUFFER bit in the gfx_capabilities flag to see if it will work with the current driver. RETURN VALUE
This function returns zero on success, non-zero otherwise. SEE ALSO
poll_scroll(3alleg4), request_video_bitmap(3alleg4), gfx_capabilities(3alleg4), scroll_screen(3alleg4) Allegro version 4.4.2 request_scroll(3alleg4)
