osd-contiki/platform/wismote/node-id.c
Adam Dunkels ec8c7e9be0 Cleanup of the node-id.h files. The node-id.h file contains
declarations of functions for setting and getting a node ID number, a
functionality that exists on many platforms. Since this functionality
was not considered part of the Contiki core, each platform defined its
own node-id.h file. This commit attempts to clean this up by
collecting the node-id.h into a core/sys/node-id.h file that replaces
the old node-id.h files from the platform directories.
