Storing function references

[Kenneth Gangstoe <kennethg@...>]

Hi.

I am in need of storing a reference to a Lua function in C, for later use.

In Lua:

function f() write("foo") end 

addEvent(10, f)


The question becomes how do I at the C side (where addEvent is implemented) 
save a reference to 'f' so that I can call 'f' asynchronously 10 seconds 
later ?
