Neither of the calls is a system call on any system that I'm aware of.
Getcwd(3) is the thing POSIX wants you to use.
Getwd() is to getcwd() what gets() is to fgets() [ well, almost ].
When chosing between: getwd(char *buf) and getcwd(char *buf, size_t size_of_buf)
the choice should be obvious.
In SunOS 4.1.x, getcwd() does call /bin/pwd.
In Solaris 2.x, getcwd() use /etc/mnttab and some tree traversal
to find the current directory. getwd is relegated to libucb.so and
just calls getcwd(buf, MAXPATHLEN);
