UDPSocket.h@90:0a988e4abb72, 2016-04-19 (annotated)

Committer:
Christopher Haster
Date:
Tue Apr 19 18:22:15 2016 -0500
Revision:
90:0a988e4abb72
Parent:
89:b1d417383c0d
Child:
92:dd5f19874adf
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
