How can I > listen to specific file or=A0directory to monitor ? I'm coding with c. If I remember correctly, what you're searching for does already exist: FAM - the File Alteration Monitor. It's in the ports collection (/usr/ports/devel/fam). There are also C++ and Ruby bindings, maybe you can also interface with C... For C: Maybe using readdir() et al. could be useful? Also see "man 5 inode", "man 5 dir" and "man 3 readdir" for more info. And struct ufs2_dinode in /usr/include/ufs/ufs/dinode.h should have the information you need to parse for; maybe also check the FILE type in /usr/include/stdio.h for access flags. --=20 Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
