Hello, A few months ago Ulrich Drepper added a family of byteorder conversion macros to glibc. I've written a rough manpage for them; attached. The colophon may have the wrong version, I just guessed it. The endian.3 file needs an big bundle of links to it, listed below: betoh64 betoh32 betoh16 htobe64 htobe32 htobe16 letoh64 letoh32 letoh16 htole64 htole32 htole16 Also, the existing byteorder.3 manpage should get a "SEE ALSO" reference to the new family: .BR endian (3) Regards, Nanno PS. Please CC me explicitly on any email, I'm not on the 'vger' list.
