bits shared by the stringobject and unicodeobject implementations (and
|
|
possibly other modules, in a not too distant future).
|
|
|
|
the stuff in here is included into relevant places; see the individual
|

source files for details.

the following defines used by the different modules:
|
|
|
|
STRINGLIB_CHAR
|
|
|
|
the type used to hold a character (char or Py_UNICODE)
|
|
|
|
STRINGLIB_EMPTY
|
|
|
|
a PyObject representing the empty string, only to be used if
|
|
STRINGLIB_MUTABLE is 0
|
|
|
|
int STRINGLIB_CMP(STRINGLIB_CHAR*, STRINGLIB_CHAR*, Py_ssize_t)
|
|
|
|
compares two strings. returns 0 if they match, and non-zero if not.
|
|
|
|
Py_ssize_t STRINGLIB_LEN(PyObject*)
|
|
|
|
returns the length of the given string object (which must be of the
|
|
right type)
|
|
|
|
PyObject* STRINGLIB_NEW(STRINGLIB_CHAR*, Py_ssize_t)
|
|
|
|
creates a new string object
|
|
|
|
STRINGLIB_CHAR* STRINGLIB_STR(PyObject*)
|
|
|
|
returns the pointer to the character data for the given string
|
|
object (which must be of the right type)
|
|
|
|
int STRINGLIB_CHECK_EXACT(PyObject *)
|
|
|
|
returns true if the object is an instance of our type, not a subclass
|
|
|
|
STRINGLIB_MUTABLE
|
|
|
|
must be 0 or 1 to tell the cpp macros in stringlib code if the object
|
|
being operated on is mutable or not
