Description[edit | edit source]
Returns a memory address which can be used to access the function specified by FunctionName. FunctionName must be the name of a function which was defined or prototyped at some earlier location in the source code (in a local fn, a def fn <expr>, or a def fn <prototype> statement).
The address returned by @fn can be used in the def fn using statement, in the fn using statement/function, or to specify a callback function (for instance a Carbon Event handler).
