[SOLVED] How do you use a typedef in a struct for which the struct is defining?

Issue

If I have this:

typedef struct {
   foo_t *bar;
} foo_t;

then I get errors like error: unknown type name ‘foo_t’. I could make bar a void* and cast later, but that seems like the wrong way to go.

Is there a proper way to resolve this chicken and egg problem?

Solution

Something like this

   typedef struct foo_t {
       struct foo_t *bar;
   } foo;

So your type is foo, which is the same as struct foo_t
