int rtnl_link_bridge_add	(	struct nl_sock *	sk,
		const char *	name
	)

Create a new kernel bridge device.

Parameters

sock	netlink socket
name	name of the bridge device or NULL

Creates a new bridge device in the kernel. If no name is provided, the kernel will automatically pick a name of the form "type%d" (e.g. bridge0, vlan1, etc.)

Returns: 0 on success or a negative error code

int rtnl_link_is_bridge ( struct rtnl_link * link )

Check if a link is a bridge.

Parameters

link	Link object

Returns: 1 if the link is a bridge, 0 otherwise.

Parameters

link	Link object of type bridge

Checks if the bridge object has been constructed based on information that is only available in newer kernels. This affectes the following functions:

Returns: 1 if extended information is available, otherwise 0 is returned.
