Declaration a function with output of enum

I have an enum declaration as below.

//declaring the situations can happen by next step
enum step {CANGO, CANTGO, WILLFALL, LOSEPOINT, GAINPOINT};

and I want to delcare a function which its output is of that declared enum. How I can do that?

Easy:

enum step myfunction();

Or if you want you could use typedef, but I wouldn't recommend it in this case:

typedef enum step step;

step myfunction();

The trick to remember is that in C, an enum type must be referred to using the enum keyword, so a plain step would not work, which is probably what you tried first.

Of course, with the typedef trick it works. You can be even lazier and write:

typedef enum step {CANGO, CANTGO, WILLFALL, LOSEPOINT, GAINPOINT} step;

But I'm on the opinion that an enum must look like an enum (a struct like an struct, and so on), and this typedef hides that.
