V - implement hard-iface init function List-Id: The list for a Better Approach To Mobile Ad-hoc Networking List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: b.a.t.m.a.n@lists.open-mesh.org Cc: Antonio Quartulli Some fields in the hard-interface data structure are specific to the B.A.T.M.A.N. V protocol and have to be initialized only when such protocol is compiled in. Instead of having a #ifdef block in the middle of the hard-interface.c code it is better to have an algorithm private function that hides the precompiler logic in its own header file (like other functions).
