Self referencing structure

[Bladactania]

I have a structure that contains a pointer to another instance of itself (like a linked list). However I'm getting an error that says I'm missing a ";" when I'm not...

typedef struct IOD {
  char Name[11];
  int  Request_Type;
  char *Transfer_Buffer;
  int  *Transfer_Counter;
  IOD  *Next_IOD;
} IOD;

I think I need some sort of prototype struct but I'm unsure how to do this.
