Initialize Static Array of Structs in C

Your approach is exactly right.

1. This will work, and is a good way to avoid huge switch statements.
2. You can’t define functions inline in C, they each must have a unique name.

3. extern is what you want, not static. Change your body to be this:

   struct CARD cardDefinitions[] = { 
       {0, 1, do_card0}, 
       {1, 3, do_card1} 
   }; 
   

   then in an appropriate header file:

   extern struct CARD cardDefinitions[];
