+ *
+ * The following macro can be used to declare both pointers and

+ * a copy of the 'data' argument passed to _hd_scan_user_home_dirs()
+ * and is intended for the user of _hd_scan_user_home_dirs() to use
+ * to pass anonymous context data to the callback function.
+ * The username and home directories are passed to the callback function
+ * in the *usrnam and *homedir arguments respectively.
+ * To abort the scan, and have _hd_scan_user_home_dirs() return 1, the
+ * callback function can return 1. A description of up to maxerr
+ * characters before the terminating '\0', can be written to errmsg[].
+ * This can then be examined by calling _hd_last_home_dir_error().
+ * To indicate success and continue the scan, the callback function
+ * should return 0. _hd_scan_user_home_dirs() returns 0 on successful
+ * completion of the scan, or 1 if an error occurred or a call to the
+ * callback function returned 1.
