change code

[wolfnether]

new version

[wolfnether]

router program no significant change
routerapi change protocol
mcn new version

Hey wolfnether,
it's generally considered bad etiquette to bump a thread with multi-posts.
There aren't any specific rules against that here as far as I know, but I'd advise using the edit-function nonetheless.
Lest you might achieve the opposite of what you were possibly aiming for (i.e. pissing people off).
Just friendly advice, no offense. />

[Yurameki]

Excuse my ignorance here, but what method is this API meant to be used by? Are we expecting to call this from other programs alone, or is something meant to be running on an existing set of systems somewhere, adding nodes as it runs? Maybe I'm just having trouble reading the code.

[wolfnether]

sorry but i don't understand :s

and i have debugged the code!
