/*
NAME
getcwd -- get absolute pathname for current working directory
SYNOPSIS
char *getcwd (char pathname[len], len)
DESCRIPTION
Copy the absolute pathname for the current working directory into
the supplied buffer and return a pointer to the buffer. If the
current directory's path doesn't fit in LEN characters, the result
is NULL and errno is set.
BUGS
Emulated via the getwd() call, which is reasonable for most
systems that do not have getcwd().
