Revision:
90:0a988e4abb72
Parent:
89:b1d417383c0d
Child:

Add open call as alternative to passing NetworkInterface at construction



Pros

- Allows memory to be statically allocated

- Avoids issues with Thread creation before entering main

- Matches existing APIs such as FunctionPointer and Ticker



Cons

- Does not enforce passing a NetworkInterface
