Creates a zero-size "userdata" object, optionally with a sharable empty metatable.
obj = newproxy(boolean or otherproxy)
- (boolean or otherproxy)
- Whether to create a metatable for the userdata.
- If an object previously created by newproxy is passed, the new userdata will share that proxy's metatable.
- Userdata (an opaque block of memory)
The newproxy function is an undocumented part of the Lua 5 base library. It is included here because it is used in the implementation of the Secure Headers added in WoW 3.0 (see FrameXML\SecureHandlers.lua), and addon authors looking over that code are likely to be curious about what it does.
