| %x | int | Exactly equivalent to printf("%x"). | 
| %s | char* | A null-terminated C character array. |

PyString_FromStringAndSize(NULL, size).
  It must not be deallocated.  If string is a Unicode object,
  this function computes the default encoding of string and
  operates on that.  If string is not a string object at all,
  PyString_AsString() returns NULL and raises
  TypeError.
| PyObject *string) | 
| PyObject *obj, char **buffer, int *length) | 
The function accepts both string and Unicode objects as input. For
  Unicode objects it returns the default encoded version of the
  object.  If length is NULL, the resulting buffer may not
  contain NUL characters; if it does, the function returns -1
  and a TypeError is raised.
The buffer refers to an internal string buffer of obj, not a
  copy. The data must not be modified in any way, unless the string
  was just created using PyString_FromStringAndSize(NULL,
  size).  It must not be deallocated.  If string is a
  Unicode object, this function computes the default encoding of
  string and operates on that.  If string is not a string
  object at all, PyString_AsStringAndSize() returns 
  -1 and raises TypeError.
| PyObject **string, PyObject *newpart) | 
| PyObject **string, PyObject *newpart) | 
| PyObject **string, int newsize) | 
0 is returned; the address in
  *string may differ from its input value.  If the
  reallocation fails, the original string object at *string is
  deallocated, *string is set to NULL, a memory exception is set,
  and -1 is returned.
| PyObject *format, PyObject *args) | 
format % args.  The args
  argument must be a tuple.
