Even better than that (I'd say), use the built-in functions of the OS: >From the Programmer's Companion:
The byte ordering macros are defined in <unix/netinet_in.h>. They convert an integer between network byte order and the host byte order. htonl Converts a 32-bit integer from host byte order to network byte order. htons Converts a 16-bit integer from host byte order to network byte order. ntohl Converts a 32-bit integer from network byte order to host byte order. ntohs Converts a 16-bit integer from network byte order to host byte order. Using these would certainly be the strandard in terms of network commuinication. Of course, it gets more fun with complex data types, but it's still workable. Been a long time since I called these functions, so please read your local C reference for more details. - Colin > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Idries > Hamadi > Sent: Wednesday, June 05, 2002 5:18 AM > To: Palm Developer Forum > Subject: RE: Byte Ordering. > > > Or even better than that, allow the sender to tell the reciever which byte > ordering it's using, and then require the reciever to convert it > to whatever > it wants.
