Declaration [src]
gboolean
g_socket_join_multicast_group_ssm (
GSocket* socket,
GInetAddress* group,
GInetAddress* source_specific,
const gchar* iface,
GError** error
)
Description [src]
Registers socket to receive multicast messages sent to group.
socket must be a G_SOCKET_TYPE_DATAGRAM socket, and must have
been bound to an appropriate interface and port with g_socket_bind().
If iface is NULL, the system will automatically pick an interface
to bind to based on group.
If source_specific is not NULL, use source-specific multicast as
defined in RFC 4604. Note that on older platforms this may fail
with a G_IO_ERROR_NOT_SUPPORTED error.
Note that this function can be called multiple times for the same
group with different source_specific in order to receive multicast
packets from more than one source.
Available since: 2.56
Parameters
group-
Type:
GInetAddressA
GInetAddressspecifying the group address to join.The data is owned by the caller of the method. source_specific-
Type:
GInetAddressA
GInetAddressspecifying the source-specific multicast address orNULLto ignore.The argument can be NULL.The data is owned by the caller of the method. iface-
Type:
const gchar*Name of the interface to use, or
NULL.The argument can be NULL.The data is owned by the caller of the method. The value is a NUL terminated UTF-8 string. error-
Type:
GError **The return location for a recoverable error.
The argument can be NULL.If the return location is not NULL, then you must initialize it to aNULLGError*.The argument will be left initialized to NULLby the method if there are no errors.In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
