    Passing members of structs to functions

    How I pass a member of a struct to a function? I can't pass the whole struct because this isn't one of my own functions. Any ideas?

    Code:
    struct my_struct {
      int x;
      int y;
    };
    
    int do_stuff(int x) {
      return 0; /* hey who said it was a useful function */
    }
    
    int main(void) {
      struct my_struct n = {1, 2};
    
      do_stuff(n.x);
    
      return 0;
    }

    Same idea...but I'm in a helpful mood today.

    Code:
    #define NAME_SIZE  8
    
    struct my_struct {
      char name[NAME_SIZE];
    };
    
    int do_stuff(char *name) {
      printf("what is your name?");
      fgets(name, NAME_SIZE, stdin);
    
      return 0; /* hey who said it was a useful function */
    }
    
    int main(void) {
      struct my_struct n;
    
      do_stuff(n.name);
    
      printf("My name is %n, and I'm addicted to programming.", n.name);
    
      return 0;
    }

    Thanks a lot. Must be something wrong with my code then but that's WINAPI - another story....

    I am plenty familiar with the WinAPI if you had a more specific question.
