Usage of “static” within a struct in C

Question

Is it legal to have a \"static\" member within a C struct?

For example

struct my_struct {
    int x;
    static int y;
};

If indeed

Answer 1

you cannot use the static specifier in a structure...

structure variables cannot be initialized inside a structure and static specifier initializes the variable to 0..

this behavior is not allowed in C..
