Passing lua functions to C

["Phil" <phil@...>]

I need to find a way to pass Lua functions to C. What I want to do is have a
C function that can be called by a Lua script, and have a lua function
passed to it. That way the script can specify which function it wants C to
call, like registering an event handler. But I can't seem to find anything
in the FAQ or manual about how to do this. Any help is appreciated.

Thanks, Philip Bock
