IP_DROP_SOURCE_MEMBERSHIP2const
Leave a source-specific multicast group
Usage
#include <netinet/in.h> /* Definition of IP* constants */ #include <sys/socket.h>
int setsockopt(int sockfd, IPPROTO_IP, IP_DROP_SOURCE_MEMBERSHIP, const struct ip_mreq_source *val, sizeof(struct ip_mreq_source));
Library
Standard C library (libc, -lc)
Overview
Leave a source-specific group; that is, stop receiving data from a given multicast group that comes from a given source.
If the application has subscribed to multiple sources within the same group, data from the remaining sources will still be delivered. To stop receiving data from all sources at once, use IP_DROP_MEMBERSHIP(2const).
Errors
See IPPROTO_IP(2const). See setsockopt(2). See ip(7).
