Callbacks with a limited scope - Geebrox - 21.05.2018

Hi, is it possible to create callbacks with a limited scope? I need callbacks which are available only in the include file. I know that it is possible to create functions with a limited scope through "static".

Код:

//For instance, file "some_inc.inc"
static SomeFunc() { } //wiil be available only in this file

How can I do the same thing with callbacks? Is this possible?

Why I need this? Because I can't use timers for functions.

Re: Callbacks with a limited scope - Geebrox - 22.05.2018

This is possible

I just checked.
If someone interested, I used:

Код:

//File "some_inc.inc"
static @SomeFunc();
static @SomeFunc() { }
//@SomeFunc is available only in this file.

P.S.
But it works a little bit different rather than "static" functions.
If someone has other methods, please share.

Any ideas? (up)

Declare static variable & function wille make them only available in the current file. There is no other better method. What's the problem with the "static" keyword?

Thank you for answers.

But there is a bug of the compiler. As DC (Daniel_Cortez) tested, there is some possible way to do it.

myinc.inc

PHP код:



static @SomeFunc();

static @SomeFunc()

{

    emit const.pri 0;

}

main.p:

PHP код:



#include "myinc.inc"

 

@SomeFunc();

@SomeFunc()

{

    emit const.pri 1;

}

 

main()

{

    @SomeFunc();

}

Output pawndisasm:

PHP код:



00000000  halt 00000000

 

00000008  proc     ; @SomeFunc

0000000c  const.pri 00000000

00000014  zero.pri

00000018  retn

 

0000001c  proc     ; @SomeFunc

00000020  const.pri 00000001

00000028  zero.pri

0000002c  retn

 

00000030  proc

00000034  push.c 00000000

0000003c  call 0000001c    ; @SomeFunc

00000044  zero.pri

00000048  retn

But you cannot know which one is exactly will be called and in which file

And you want to say that this is what I wanted?

And as I understood, it doesn't work as seemed to ******:

Re: Callbacks with a limited scope - CodeStyle175 - 22.05.2018

you dont want to create global function but you want to call it from other include?

Edit: But this method isn't overly useful, as it requires having two copies of the function - one public shadowing the static version.

Yes, you were right, sorry)

But I need timers. If I use timers the result is different
