I would like to say that the previous post I made "Sending data with CFSocket" should be ignored. After reading over a faq I found I'm 99% positive the sending error is because I failed to convert some of the address struct members to network byte order.

FWIW, you are running your program on a PowerPC CPU, which is big-endian, which is, by a happy coincidence, just what network byte-order is defined to be (at least, for the IP family, and other right-thinking protocols).


I tried to make a test project in CW that could make the calls to convert to network byte order and found that I don't know where the library is that contains the functions in the headers listed below. Does anyone know where these can be found? Thanks for your help.

netinet/in.h
arpa/inet.h

These should be available in the system framework, which is referenced automatically, when you compile.


If you are having a specific problem, perhaps a few details would help (I don't feel like verifying that every call defined in these headers is in the system framework).

Also, again, FWIW, if host- and network-byte-order are the same, it's likely that the relevant reordering functions are no-ops.

Cheers,

Justin
