Using data types before they are declared.

[August Wehrmann]

I have a question: 

Is it possible, (and if so, how?), to use a data type in a declaration
of say, a union, that has not yet been declared?

Here is an example of what I'm talking about.

union Fred {              <--------
	int 	Number;            |
	element	Node;     <...........
};                                 | .
                                   | .
typedef struct {                   | .
	int	Info;              | .
	Fred	Name;     <--------  .
} *element;               <...........


Please e-mail any replies. Quick references to Kernighan and Ritchie would also
be appreciated.

Thanks in advance.
