Method
GioSocketjoin_multicast_group
since: 2.32
Declaration [src]
gboolean
g_socket_join_multicast_group (
GSocket* socket,
GInetAddress* group,
gboolean 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 TRUE
, source-specific multicast as defined
in RFC 4604 is used. Note that on older platforms this may fail
with a G_IO_ERROR_NOT_SUPPORTED
error.
To bind to a given source-specific multicast address, use
g_socket_join_multicast_group_ssm()
instead.
Available since: 2.32
Parameters
group
-
Type:
GInetAddress
A
GInetAddress
specifying the group address to join.The data is owned by the caller of the method. source_specific
-
Type:
gboolean
TRUE
if source-specific multicast should be used. 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.

.If the return location is not NULL
, then you must initialize it to aNULL

.The argument will be left initialized to NULL
by 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.
