[AD] Allegro 4.3 file location API

[Peter Hull <peter.hull90@xxxxxxxxxx>]

I added some thoughts about a file location API to the wiki: 
http://awiki.tomasu.org/bin/view/Main/FileSystems

Here's what I wrote:

Different platforms store files in different places, so paths can't be 
hardcoded. I propose a simple API like this:
enum FILE_LOCATION
{
        SYSTEM_SETTINGS,
        APP_RESOURCES,
        USER_SETTINGS
};

const char* get_file_location(enum FILE_LOCATION);
void set_app_identifier(const char*);


The 'app identifier' is a 'unique' name for your application (could be 
a reversed domain name » like Java), so for example on Unix-like 
systems:
SYSTEM_SETTINGS -> /usr/local/share/allegro/
APP_RESOURCES -> /usr/local/share/${APP_ID}/
USER_SETTINGS -> ${HOME}/.allegro/$(APP_ID}/

 On Windows: (need to check this, anyway there are W32 Shell API 
functions to get these)
SYSTEM_SETTINGS -> c:\documents and settings\all users\application 
data\allegro\
APP_RESOURCES -> c:\program files\%APP_ID%\
USER_SETTINGS -> c:\documents and settings\%USER%\application 
data\%APP_ID%\

 System settings wouldn't be used much, only by things like the 'setup' 
program.


 What do you think?
