request_scroll(3alleg4) Allegro manual request_scroll(3alleg4)NAME
request_scroll - Queues a hardware scroll request with triple buffering. Allegro game programming library.
int request_scroll(int x, int y);
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.
This function returns zero on success, non-zero otherwise.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

Here are some examples of what I've tried:
