Yes, but all usages of htonlsab()/ntohlsab() are non-overlapping. (overlapping/on place usage was replaced with htonlsab1()/ntohlsab1()). > Might as well do that for these too: > +static inline void htonlsah(struct ospf_lsa_header *h, struct > ospf_lsa_header *n) { *n = *h; }; > +static inline void ntohlsah(struct ospf_lsa_header *n, struct > ospf_lsa_header *h) { *h = *n; }; *n = *h should be OK even if n == h, AFAIK. -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santi...@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
