Your objections do not extend to getcwd(), correct? Many functions
implicitly use the current directory, and I don't see what is gained by not
providing a way to query it. If you supply a make_absolute() function (which
is a good idea) it would be trivial to emulate getcwd() anyway.
About setcwd(). Perhaps a good design shouldn't need to use it.
Unfortunately code often interacts with not-so-well designed third-party
libraries. :-) You'll simply force programmers to use the non-portable
equivalent. POSIX provides one:
"The chdir( ) function shall cause the directory named by the path name
pointed to by the path
argument to become the current working directory; that is, the starting
point for path searches
for path names not beginning with '/'."
You can always ignore setcwd() on a platform without directories.
