Does anybody out there know of an easy way to get the current directory
from within a C program?  Easy meaning not using popen ("pwd ... or
system ("pwd > ...  The envp argument to main doesn't include this
information.  We'd also like to avoid explicitly passing it from the
shell, as an argument or whatever.  Is the only choice to hack pwd.c
into a subroutine?  If so, and you've already done so, we'd appreciate
a copy.

Thanks in advance.
