Hello guys!

I'm programming ICE in C, and because I haven't written any C before, I have some questions.
  • How can I define a structure to be located at location X, and then I push/pop to it? I've now this code:

    Code:
    typedef struct outputStack {
        uint8_t  type;
        uint24_t operand;
        size_t   size;
    };

    with

    Code:
    struct outputStack *outputPtr;
        outputPtr = (struct outputStack *) (uint24_t*)0xD62C00;
       
        outputPtr.size = 0;

    but that doesn't work Sad
  • More follows...

Thanks in advance! Smile

If your goal is making a puzzle "it doesn't work" might be okay, but if you're asking for help it's spectacularly unhelpful. What happens? What do you expect to happen?

Fortunately I spotted what is probably your problem- accessing struct members through pointers must use the -> operator:
Code:
struct foo *foo = malloc(sizeof(struct foo));
foo->bar = 0;
