(C) How would I save a file to a different folder which is the users home?

anon02 · 10-26-2011, 05:39 AM

I am trying to make my program save the settings in /home/USERNAME/.crimson_swarm, and to do this from within /usr/bin. The only issue is that if my username was ben, it would be /home/ben. If it was paul however, it would be /home/paul.

My question is, how can C access the users home directory from a different location?

Also, if anyone knows, what is the environment variable for Windows?

Code:

getenv("HOME")

Note that it's possible for it to fail if the $HOME variable is not set (not that it's likely, but I would make it exit cleanly if that happens).

How would I use that in code? Would it be:

Code:

home * getenv("HOME");

Or are there other methods?

I have no idea what you mean here, "home" is not a type.

Anyway, if you're not sure how to use it, just search: https://duckduckgo.com/?q=c+getenv

Ah, thanks. By 'home', I meant it as in 'char'. I managed to get it work... but only for linux. I tried compiling it for Windows, yet getenv("HOME") returns null. Is there a way to get it for Windows?
