Yes, but the OP seems interested in standards conformance and whether another compiler would compile this code the same. It probably would thouch (especially in c99).

request_scroll

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.
