This is a QoS-enabled method for joining a multicast group, which passes <qos_params> via <ACE_OS::join_leaf>. The network interface device driver is instructed to accept datagrams with <mcast_addr> multicast addresses. If the socket has already been opened, <subscribe> closes the socket and opens a new socket bound to the <mcast_addr>. The session object specifies the QoS session that the socket wants to subscribe to. A socket may subscribe to multiple QoS sessions by calling this method multiple times with different session objects.
The <net_if> interface is hardware specific, e.g., use "netstat -i" to find whether your interface is, such as "le0" or something else. If net_if == 0, <subscribe> uses the default mcast interface. Returns: -1 if the call fails.
Note that some platforms, such as pSoS, support only number, not names, for network interfaces. For these platforms, just give these numbers in alphanumeric form and <subscribe> will convert them into numbers via <ACE_OS::atoi>.
