Well, you could use strtok_r if you just need re-entrancy and
multihreading. However there is another difference between strtok and
strsep. If you try to split a string like "a//b" with "/" with strtok
you get "a", "b" while with strsep you get "a", "", "b". So passing
server/username/password if username and password are empty (something
like "server//") with strsep you get empty username and password (that
is Kerberos!).
