How to create a 'static' variable for a struct in C

Question

I would like to have a struct that functions like this:

struct

• member 1 (every instance of the struct has its own value of this)

• static member (every struct shares this member)

I am aware that the static keyword does not do this. My question is, how can I mimic this behavior?

Could I create a member that is pointer to a global variable?

Is there some other better way to do this?

Answer 1

Unlike structs in C++ which can have static data members, C structs don't have such a construct.

Since this is a common value for anyone that may use it, just declare it as a global:

int my_struct_common_val = 42;

struct my_struct {
    ...
};
