A "DIRECTIVE" is not very big:


/* A parsed directive.  */
typedef struct
{
  const char* dir_start;
  const char* dir_end;
  int flags;
  const char* width_start;
  const char* width_end;
  size_t width_arg_index;
  const char* precision_start;
  const char* precision_end;
  size_t precision_arg_index;
  char conversion; /* d i o u x X f F e E g G a A c s p n U % but not C S */
  size_t arg_index;
}
char_directive;
