three_finger_flag(3alleg4) Allegro manual three_finger_flag(3alleg4)NAME
three_finger_flag - Flag to deactivate the emergency exit key combination. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
extern int three_finger_flag;
DESCRIPTION
The DJGPP keyboard handler provides an 'emergency exit' sequence which you can use to kill off your program. If you are running under DOS
this is the three finger salute, ctrl+alt+del. Most multitasking OS's will trap this combination before it reaches the Allegro handler, in
which case you can use the alternative ctrl+alt+end. If you want to disable this behaviour in release versions of your program, set this
flag to FALSE.

install_keyboard - Installs the Allegro keyboard interrupt handler.
SYNOPSIS
#include <allegro.h>
int install_keyboard();
DESCRIPTION
Installs the Allegro keyboard interrupt handler. You must call this before using any of the keyboard input routines. Once you have set up
the Allegro handler, you can no longer use operating system calls or C library functions to access the keyboard.
Note that on some platforms the keyboard won't work unless you have set a graphics mode, even if this function returns a success value
before calling set_gfx_mode. This can happen in environments with graphic windowed modes, since Allegro usually reads the keyboard through
the graphical window (which appears after the set_gfx_mode call). Example:
allegro_init();
install_timer();
install_keyboard();
/* We are not 100% sure we can read the keyboard yet! */
if (set_gfx_mode(GFX_AUTODETECT, 640, 480, 0, 0) != 0)
abort_on_error("Couldn't set graphic mode!");
/* Now we are guaranteed to be able to read the keyboard. */
readkey();
RETURN VALUE
Returns zero on success, or a negative number on failure (but you may decide not to check the return value as this function is very
unlikely to fail).

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
