set_uformat - Set the global current text encoding format. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void set_uformat(int type);
DESCRIPTION
Sets the current text encoding format. This will affect all parts of Allegro, wherever you see a function that returns a char *, or takes a
char * as a parameter. `type' should be one of these values:
U_ASCII - fixed size, 8-bit ASCII characters
U_ASCII_CP - alternative 8-bit codepage (see set_ucodepage())
U_UNICODE - fixed size, 16-bit Unicode characters
U_UTF8 - variable size, UTF-8 format Unicode characters
Although you can change the text format on the fly, this is not a good idea. Many strings, for example the names of your hardware drivers
and any language translations, are loaded when you call allegro_init(), so if you change the encoding format after this, they will be in
the wrong format, and things will not work properly. Generally you should only call set_uformat() once, before allegro_init(), and then
leave it on the same setting for the duration of your program.

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:
$ ls -ld /usr/bin /usr/bin/cat

sort -nr --key=1 ....

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.
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.
