Re: Writing portable code

[Lyle Underwood <lyleunderwood gmail com>]

Hey,

I think you might be coming at this from the wrong direction. This is
how I've generally seen people do OS specific stuff. I've only ever
bothered with directory separators and file roots before, but I'm pretty
sure these would work. Probably not the prettiest solution, and I really
didn't bother to check if Glib had some kind of API to this.

#ifdef WIN32
directory_separator = "\\"
username            = GetUserName // should work, win32 api
data_directory      = "C:\\" << username << "\\whatev"
GlobalMemoryStatus() // win32
#else 
directory_separator = "/"
username            = getlogin() or cuserid() // unistd.h, stdio.h
sysinfo // for memory size, sys/sysinfo.h
#endif

Pseudo-code obviously, but you get the idea. Should get you up and
running anyway.
