The following are 13 code examples for showing how to use socket.IP_ DROP _MEMBERSHIP().These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don’t like, and go to the original project or source file by following the links above each example .
IP_ADD_MEMBERSHIP and IP_DROP_MEMBERSHIP. Use the IP_ADD_MEMBERSHIP option to join an IPv4 multicast group on a local IPv4 interface. Use the SETSOCKOPT API and specify the address of the IP_MREQ structure that contains these addresses. The application can join multiple multicast groups on a single socket it also can join the same group on …
6.5 IP_DROP_MEMBERSHIP. The process is quite similar to joining a group: struct ip_mreq mreq setsockopt (socket, IPPROTO_IP, IP_DROP_MEMBERSHIP, &mreq, sizeof(mreq)) where mreq is the same structure with the same data used when joining the group. If the imr_ interface member is filled with INADDR_ ANY , the first matching group is dropped.
Use IP_ADD_MEMBERSHIP and IP_ DROP _MEMBERSHIP to switch multicast groups listened for by the recieving socket. Use IP_MULTICAST_LOOP if you would like the sender to also receive a copy of what is sent to the group. I don’t believe IP_MULTICAST_IF or IP_MULTICAST_TTL will be of interest for what we’re doing.

Working on a project that sends multicast data packets, and the receivers can opt in/out of the group as necessary. I noticed there are two ways of joining/leaving the groups: IP_ADD_MEMBERSHIP/, In this example, the socket is joined to the multicast group 234.5.6.7 on the local interface 157.124.22.104. Multiple groups may be joined on the same socket on the same or different interface. Once one or more multicast groups are joined, the IP_DROP_MEMBERSHIP option is.
Hi, I have checked this, and it does send out the leave group message. Can you please tell me how you are checking this? When you call sl_SetSockOpt with SL_IP_ DROP _MEMBERSHIP, an IGMP message should be sent to 224.0.0.2 indicating that the device has.
#define IP_MULTICAST_IF 32 #define IP_MULTICAST_TTL 33 #define IP_MULTICAST_LOOP 34 #define IP_ADD_MEMBERSHIP 35 #define IP_ DROP _MEMBERSHIP 36 IP_ADD_MEMBERSHIP. A process can join to a multicast group sending this option over a socket with the function setsockopt(). The parameter is a ip_mreq struct.
Data sent to the joined group is accepted regardless of the source. Once the group is joined, then the IP_BLOCK_SOURCE option is called to exclude the given source. Again, the struct ip_mreq_source structure is the input parameter that specifies the source to block. The following example joins a group and then excludes a single source:, An application can, separately from the scope of the multicast address, use different hop limit values. For example , an application might perform an expanding-ring search for a network resource by sending a multicast query, first with a hop limit of 0, and then with larger and larger hop limits, until a …
