NAME¶

IP_DROP_SOURCE_MEMBERSHIP - leave a source-specific multicast group

LIBRARY¶

Standard C library (libc, -lc)

SYNOPSIS¶

#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));

DESCRIPTION¶

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).

HISTORY¶

Linux 2.4.22, Linux 2.5.68.
