poll_mouse(3alleg4) Allegro manual poll_mouse(3alleg4)NAME
poll_mouse - Polls the mouse. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int poll_mouse();
DESCRIPTION
Wherever possible, Allegro will read the mouse input asynchronously (ie. from inside an interrupt handler), but on some platforms that may
not be possible, in which case you must call this routine at regular intervals to update the mouse state variables. To help you test your
mouse polling code even if you are programming on a platform that doesn't require it, after the first time that you call this function
Allegro will switch into polling mode, so from that point onwards you will have to call this routine in order to get any mouse input at
all, regardless of whether the current driver actually needs to be polled or not.
RETURN VALUE
Returns zero on success, or a negative number on failure (ie. no mouse driver installed).

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:

drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin

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)
I'm trying to install a PGX32 video card on my Sparc 10 Ultra running Solaris 10.
I've got the Oracle installation guide for it and I got as far as:

I don't have a CD-ROM by that name and a web search for that... (21 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.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.
The prompt is... (2 Replies)

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
But what a book. The one I found and ordered is BSD Unix®... (0 Replies)
