Variable Documentation

linkaddr_node_addr [1/2]

linkaddr_t linkaddr_node_addr

The link-layer address of the node.

        This variable contains the link-layer address of the
        node. This variable should not be changed directly;
        rather, the linkaddr_set_node_addr() function should be
        used.

linkaddr_node_addr [2/2]

linkaddr_t linkaddr_node_addr

The link-layer address of the node.

        This variable contains the link-layer address of the
        node. This variable should not be changed directly;
        rather, the linkaddr_set_node_addr() function should be

linkaddr_null

const linkaddr_t linkaddr_null

extern

The null link-layer address.

        This variable contains the null link-layer address. The null
        address is used in route tables to indicate that the
        table entry is unused. Nodes with no configured address
        has the null address. Nodes with their node address set
        to the null address will have problems communicating
        with other nodes.
