setsourcefilter function
The setsourcefilter inline function sets the multicast filter state for an IPv4 or IPv6 socket.
Syntax
int setsourcefilter( _In_ SOCKET Socket, _In_ ULONG Interface, _In_ const SOCKADDR *Group, _In_ int GroupLength, _In_ MULTICAST_MODE_TYPE FilterMode, _In_ ULONG SourceCount, _In_ const SOCKADDR_STORAGE *SourceList );
Parameters
- Socket [in]
-
A descriptor that identifies a multicast socket.
- Interface [in]
-
The interface index of the multicast interface.
- Group [in]
-
A pointer to the socket address of the multicast group.
- GroupLength [in]
-
The length, in bytes, of the socket address pointed to by the Group parameter.
- FilterMode [in]
-
The multicast filter mode for the multicast group address.
- SourceCount [in]
-
The number of source addresses in the buffer pointed to by the SourceList parameter.
- SourceList [in]
-
A pointer to a buffer with the IP addresses to associate with the multicast filter.
Return value
On success, setsourcefilter returns NO_ERROR (0). Any nonzero return value indicates failure and a specific error code can be retrieved by calling WSAGetLastError.
| Error code | Meaning |
|---|---|
|
Insufficient buffer space is available. | |
|
The descriptor is not a socket. |
Remarks
The setsourcefilter inline function is used to set the multicast filter state for an IPv4 or IPv6 socket.
This function is part of socket interface extensions for multicast source filters defined in RFC 3678. An app can use these functions to retrieve and set the multicast source address filters associated with a socket.
