Stack idea

[bergen110]

Hello,

I have the idea to make a sort of stack in C that writes to a memory location.
But is this idea efficient? or are there better ways to store fast a variable, if you need to use it short after you store it?

Yo,

Code: Select all

int myFunction(void)
{
   int myLocalArg;

   // Do something;
};

The answer to your question is on line 3.

I've made a fault in my starting post. i want to use it in another function.
I know that i can use global vars, but a simple call to a function that writes it to a memory location i simpler?

Like alloca() ?

Yes, thats the solution, thanks!
i am going to implement that function

It's a compiler intrinsic. It comes with GCC.

So i can use it without writing it?
Pretty cool!
