You can use the Computer Cabling Redundancy Socket Status API to monitor the state of all the sockets currently in use by CIMPLICITY Computer Cabling Redundancy.
The following C program prints out the status of each of the sockets.
#include <string.h>
#include <inc_path/cor.h>
#include <inc_path/redwinsock.h>
void print_sockaddr_in(struct sockaddr_in *addr);
TCHAR *socketUse[] =
{
_T("None"),
_T("Listen"),
_T("Connect"),
T("Accept"),
};
TCHAR *socketState[] =
{
_T("None"),
_T("Connecting"),
_T("Connected"),
};
int main()
{
HANDLE dwChangeHandle;
dwChangeHandle = FindFirstSocketChangeNotification();
if(dwChangeHandle == INVALID_HANDLE_VALUE)
return 0;
