Fork of NetworkSocketAPI by NetworkSocketAPI

NetworkInterface.h@94:644df37bb05b, 2016-04-19 (annotated)

Committer:
Christopher Haster
Date:
Tue Apr 19 18:23:58 2016 -0500
Revision:
94:644df37bb05b
Parent:
93:65a9f84862f0
Child:
95:b3c679f20d13
Added support for storing bytes directly in SocketAddress



Bytes are stored by default, however enough space is allocated in

a SocketAddress to generate the string representation if necessary.



Currently there is no support for shortened addresses
