 *
 *      This program is in the public domain
 *
 *      pw_openfile should usually be regarded as an internal function for
 *      the use of the passwd library only.  However, if your software has
 *      its own way of specifying the location of the password file, you may
 *      wish to use pw_openfile to pass that location to the library.
