I have find the function I need. But I have several questions: 1. why we declare variables like below: char *uuid = uuid; /* for compiler */ char *label = label; (is this special for compiling?) 2. does mdev.conf support "\d" metadata? since "sd[a-zA-Z]\d+ 0:0 0660 * xxxxxxxxx" does not work but"sd[a-zA-Z][0-9+ 0:0 0660 * xxxxxxxxx" works. doest that mean xregcomp doesn't support metadata? appreciate your all kind help:) miloody _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
