Subsequent code to check the socket's status, something like:
int n;
socklen_t intsize = sizeof(int);
getsockopt(f, SOL_SOCKET, SO_ERROR, (void*)&n, &intsize);
if (n) ...
which works (with suitable cast adjustments) on Solaris, Linux,
Darwin, and yes, even on Windows, doesn't work here.
inline bool sockreq() { return bSocketsRunning; }
it could be a simple script, or it could become a socket array of
nightmares.. but it is no oubt a god idea to always check the sockets.
