# /usr/sbin/lsof /usr/lib/libwrap.so*
COMMAND    PID     USER  FD   TYPE DEVICE  SIZE  NODE NAME
sshd      2287     root mem    REG  253,0 32856 89881 /usr/lib/libwrap.so.0.7.6

rpc.rquot 3001     root mem    REG  253,0 32856 89881 /usr/lib/libwrap.so.0.7.6

In the above example, the lsof command returned a list of running programmes using TCP wrappers. If the tcp_wrappers package is updated, all the above programmes would have to be stopped and restarted.
