    (struct s) {.one = 1}; Is this C99?

    Is this C89? Or C99?

    Code:
    #include <stdio.h>
    
    struct s {
        int one, two;
    };
    
    void func(struct s structure) {
        printf("%i %i\n", structure.one, structure.two);
    }
    
    int main(void) {
        func((struct s) {.one = 5});
        func((struct s) {1});
        func((struct s) {.two = 3, .one = 1});
    
        return 0;
    }

    It's C99 if I recall correctly.
    My best code is written with the delete key.

    It is definitely c99 only. It was not supported in C89. Although some compilers before C99 may have supported such a feature as a non-standard extension.
