[erlang-questions] Erlang introspection
Wed Nov 26 02:46:43 CET 2008
If both sides are erlang you can send the actual fun(), otherwise, on the receiving end you can do list_to_atom on the function name and then call the function with the arguments. For instance you could do something like this.
you've received a string "fun_name", with arguments A, B, C.
Func = list_to_atom("fun_name"),
Of course you need the actual function to exist and the parameters to be valid. And IMHO, you also really don't want to be doing stuff like this over a network unless you are VERY careful.

receives and function name and arguments through a socket and I'd like to use
this information to make a function call on the module that receives it. Can
anyone suggest a good starting point for finding out how to do
