I create two C files, one is main.c and another is test.c,and then I defined an struct verb in test.c:
struct image{
int a;
char b;
};
struct image ss;

void test() {
ss.a = 10;
}
I want to use the struct verb ss in the main.c,but I failed. Please help me how can I use the struct verb ss in the main.c.
Thank you very much
