Using a variable as structure identifier

Question

I've got a small question regarding dynamic structure definitions. When declaring a structure definition under ANSI-C, is it possible to use a "string"-variable as a structure identifier like below?

*(a_string_var) = "username";
struct user *(a_string_var);

What do you expect this to do? The answer is no, anyway, but what's it supposed to mean? — hobbs

@hobbs I think the intention would be a struct user variable named username. — Justin Spahr-Summers

My intention indeed was to create a structure with a variable identifier. To be more specific to create a username starting with the first letter of the firstname, and the full surname. I know i can create an array of structs, but in that case the structure identifier would become something like user[0]. but that's something i've been trying to avoid. — D Jake

No, all declarations in C must use static, inline identifiers.
