The RasEnumConnections function lists all active RAS connections. It returns each connection's handle and phone-book entry name.
DWORD RasEnumConnections(
LPRASCONN lprasconn, // buffer to receive connections data
LPDWORD lpcb, // size in bytes of buffer
LPDWORD lpcConnections
// number of connections written to buffer
);
If the function succeeds, the return value is zero.
If the function fails, the return value is a nonzero error value listed in the RAS header file or one of ERROR_BUFFER_TOO_SMALL or ERROR_NOT_ENOUGH_MEMORY.
If a connection was made without specifying a phone-book entry name, the information returned for that connection will give the connection phone number preceded by ".".
