Sorry to keep hammering on this, but I'm trying to learn :). Is this any good? And yes, I care about memory leaks. I can't find a decent way of preallocating the char*, because there simply seems to be no cross-platform way.
const string getcwd()
{
char* a_cwd = getcwd(NULL,0);
string s_cwd(a_cwd);
free(a_cwd);
return s_cwd;
}
UPDATE2: without Boost or Qt, the most common stuff can get long-winded (see accepted answer)
