remove_display_switch_callback(3alleg4) Allegro manual remove_display_switch_callback(3alleg4)NAME
remove_display_switch_callback - Removes a switching notification callback. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void remove_display_switch_callback(void (*cb)());
DESCRIPTION
Removes a notification callback that was previously installed by calling set_display_switch_callback(). All the callbacks will automati-
cally be removed when you call set_display_switch_mode(). You can safely call this function even if the callback you want to remove is not
installed.

set_display_switch_callback - Installs a switching notification callback. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int set_display_switch_callback(int dir, void (*cb)());
DESCRIPTION
Installs a notification callback for the switching mode that was previously selected by calling set_display_switch_mode(). The direction
parameter can either be SWITCH_IN or SWITCH_OUT, depending whether you want to be notified about switches away from your program or back to
your program. You can sometimes install callbacks for both directions at the same time, but not every platform supports this. You can
install several switch callbacks, but no more than eight on any platform.
RETURN VALUE
Returns zero on success, decreasing the number of empty callback slots by one. Returns -1 if the request is impossible for the current
platform or you have reached the maximum number of allowed callbacks.

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

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.

Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
Many tricky terminal escape codes are not catered for so I had to create workarounds.
One thing I searched for was this:

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).

This is purely a fun project to see if it is possible in PURE... (3 Replies)
