Reading passwd structures from a file other then /etc/passwd

I am writing a program that will read passwd structs, but I do not wish to play with /etc/passwd just yet for obvious reasons. So how do I "redirect" getpwent() to read from my "safe" copy?

cp -p /etc/passwd /etc/passwd.old,
ln -s /etc/passwd /path/newfile.

I already have a copy of the file. I've been looking for something like the utmpname() function, but fgetpwent() doesn't quite seem to do it.
