- Janice Caron (3/6) May 20 2008 I never did understand the difference between ntoh* and hton*. :-)
- Ingo Oeser (7/8) May 24 2008 It is a semantic difference only, not a behavioral one.

http://d.puremagic.com/issues/show_bug.cgi?id=2117 Summary: Please add more byteswapping support Product: D Version: 2.014 Platform: PC OS/Version: Linux Status: NEW Severity: enhancement Priority: P2 Component: Phobos AssignedTo: bugzilla digitalmars.com ReportedBy: jlquinn optonline.net Right now there is limited support for byteswapping. std.intrinsic includes bswap(uint), and std.system includes a predefined constant for system endianness. It would be really helpful to have bswap equivalents for all basic datatypes, as well as routines to swap between native endianness and explicit big or little endian, ala ntohl, ntohs, htonl, htons A related thing that would come in handy is byteswapping mmap support. --

You can deduce the expected and actual endianess when using the semantically correct transformation. This helps (static) checkers like e.g. sparse on Linux. Best Regards Ingo Oeser
