(Jass) Libraries, scopes and calling functions inside them

[gengar]

Hi, I'm posting this because i would like to make good spell system, however:
I have a library, where are functions which runs everytime some spell of the pack is cast, because all of them uses same functions. I need every single spell to have own library or scope or something, with functions, which will be called from the basic spell library.
The problem is that, I don't know how to let the function (in base library) know which spell did it, so it can call the right scope (all scopes has the same functions)
Ask if you do not understand me

Thanks for all tips and comments
+rep for help

I tried to pass them CODE, but i dont know how to convert code to function

    function Effect takes unit caster, unit u, code ef, code dmg returns nothing
        call UnitDamageTarget(caster, u, dmg, true, false, ATTACK_TYPE_NORMAL, DAMAGE_TYPE_NORMAL, WEAPON_TYPE_WHOKNOWS)
        call ef (caster, u)
    endfunction

//...........................

function Wave1 takes unit caster, integer n1, code u1, code ef1, code dmg1 returns nothing
        local unit u
        local group gr     // i will put some units to the group later ... do not care
        
        loop 
            exitwhen(gr == null)
            u=FirstOfGroup(gr)
            if u1(u)==TRUE then
                call Effect( caster, u, ef1, dmg1)
            endif
            GroupRemoveUnit(gr, u)                
        endloop
    endfunction

I need somthing like a link variable, which can point to my function.
From C programming language I know that, we can use Pointers, is there such a thing? If yes, i could just pass the function pointer to functions i need to run...

I am not sure exactly what you're trying to do. =\

So you have a base spell thing. And then it extends to call different scopes based on what spell it is? Can't you just use GetSpellAbilityId() == Rawcode 'xxxx'?

Or am I missing something...

For that function, you can only use code if it doesn't take arguments. If you can't explain the problem, you can try posting an example of the libraries that you want to call or something. Are you trying to pass arguments through to a different function?

Just use some integer array that has the rawcodes of the abilities that share the same functions and add an if/then/else statement to define which one of those arrays was called.
Pretty much what PurgeandFire111 said.
