} while (0)

MOD_DIR_FORWARD_DECLARE

#define MOD_DIR_FORWARD_DECLARE

(

name

)

Value:

static PyObject* _##name##__dir__(name *self)

Macros that can be used to simplify way of generating dir content that is necessary for executing dir() on an object.

MOD_DIR_FUNCTION

#define MOD_DIR_FUNCTION	(		name,
			method_listing )

Value:

  static PyObject * _##name##__dir__(name *self) { \
  int i=0; \
  PyObject* rc = PyList_New(0); \
  if (!rc) \
    return NULL; \
\
  while (method_listing[i].ml_name != NULL) { \
    MOD_DIR_APPEND(rc, method_listing[i++].ml_name); \
  } \
\
  return rc; \
}

MOD_DIR_REFERENCE

#define MOD_DIR_REFERENCE

(

name

_##name##__dir__

MOD_INIT

#define MOD_INIT

(

Function Documentation

PyHlhdf_StringOrUnicode_FromASCII()

PyObject * PyHlhdf_StringOrUnicode_FromASCII	(	const char *	buffer,
		Py_ssize_t	size )

Tries to get same behaviour for the result returned when getting a string from the data node.

For 2.7 PyString_FromStringAndSize is used, for 3.x a variant of _PyUnicode_FromASCII.

PyHlhdfAPI_CompareWithASCIIString()

int PyHlhdfAPI_CompareWithASCIIString	(	PyObject *	ptr,
		const char *	name )

Tests if a python object string (or unicode) is equal to name.

Parameters

[in]	ptr	- the python string or unicode
[in]	name	- the string to compare with

Returns

0, -1 or 1
