As long as there's a layer of functions which converts numeric fields within
a data stream into the machine's internal representation of numbers, and
back again, big endian versus little endian shouldn't be a problem. Taking
care of pointer arithmetic behaviour between platforms as well, of course.
The bigger issues come up with operating system facilities, like files and
sockets.
For instance, in *nix, sockets are treated much like file descriptors, and
are compatible with file functions such as open(), close(), read(), write(),
fdopen() etc. But in windoze, there are separate socket primitives - send(),
recv() etc. Also, WSAStartup() must be called before any sockets are used.
Also, differences in file path syntax: Unix: /dir1/dir2/../dirn/filename,
Windows: C:\dir1\dir2\..\dirn\filename.ext
Also, line terminators for text files: Unix: \n, Windows: \r\n
And so on.
A very good example of portable code is the Junkbusters proxy, at
http://www.junkbusters.com/ijb.html
I feel really enthusiastic at the thought of a Freenet client in C that
compiles on Windows and Unix (perhaps Mac as well). Keep it up.
Cheers
