Of course, this is UNIX.  You can easily find the source code for the password
command (one file: passwd.c) and cut and paste the change routine into your own
code, compile, and BING!  I've also seen password change routines writen in
perl,  but I know C and not perl.  I've done alot of hacking on the security
subsysten so when you know exactly what you want to do let me know.
