winsock question

How do I get the local port of a connected socket?

getsockname() gives you (via a passed in pointer) access to a sockaddr structure for the socket - then just cast that to a sockaddr_in and access the sin_port member.

I tried that but the compiler says you can't make that cast. I assume you mean something like this?

sockaddr sa;
int sasize = sizeof(sa);
getsockname(msMain, &sa, &sasize);
sockaddr_in sintemp = (sockaddr_in)sa;
int iLocalPort = sintemp.sin_port;

You have a sample in the following article from MSDN
"Example Code for Implementing a Winsock Service with an RnR Publication"

seems like you have to use the ntoh function first.
