The function actually seems to work quite well once you understand what the goal is:
1- Ignore non-valid paths
2- Enforce POSIX minimum path of '/'
2- On Win32 jump from 'C:\' & '\\Server' style paths straight to '' path
Without these conditions the function would be:
name = GetFileTitle(dir);
dir = GetFileFolder(dir);
The only change I would make would be to remove trailing DIR_SEPs, but you can always add something like this:
if (dir.GetLength() > 1) {
const char *eos = dir.End()-1;
int cnt = 0;
while (*eos == DIR_SEP && eos > dir.Begin()) {
eos--;
cnt++;
}
if (cnt) {
#ifdef PLATFORM_WIN32
if (*eos != ':')
#endif
{
dir.Remove(dir.GetLength()-cnt, cnt);
}
}
}
