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 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)
