.TH socket_mchopcount6 3
socket_mchopcount6 \- set multicast hop count
.B #include <socket.h>
int \fBsocket_mchopcount6\fP(int \fIs\fR,char \fITTL\fR);
socket_mchopcount6 sets the maximum hop count of outgoing multicast
packets on the socket \fIs\fR. Each router decrements the packet hop
count by one and discards the packet if it reaches zero. Setting the
maximum hop count to 1, for example, will limit the packet propagation
to the LAN.
If something goes wrong, socket_mchopcount6 returns -1, setting errno
socket_mcttl4(3), socket_mcjoin4(3), socket_mcleave4(3)
