9 object PyImport_ImportModule(char *name)
10 # Return value: New reference.
11 # This is a simplified interface to PyImport_ImportModuleEx()
12 # below, leaving the globals and locals arguments set to
13 # NULL. When the name argument contains a dot (when it specifies a
14 # submodule of a package), the fromlist argument is set to the
15 # list ['*'] so that the return value is the named module rather
16 # than the top-level package containing it as would otherwise be
17 # the case. (Unfortunately, this has an additional side effect
18 # when name in fact specifies a subpackage instead of a submodule:
19 # the submodules specified in the package's __all__ variable are
20 # loaded.) Return a new reference to the imported module, or NULL
21 # with an exception set on failure.
23 object PyImport_ImportModuleEx(char *name, object globals, object locals, object fromlist)
24 # Return value: New reference.
26 # Import a module. This is best described by referring to the
27 # built-in Python function __import__(), as the standard
28 # __import__() function calls this function directly.
30 # The return value is a new reference to the imported module or
31 # top-level package, or NULL with an exception set on failure
32 # (before Python 2.4, the module may still be created in this
33 # case). Like for __import__(), the return value when a submodule
34 # of a package was requested is normally the top-level package,
35 # unless a non-empty fromlist was given. Changed in version 2.4:
36 # failing imports remove incomplete module objects.
38 object PyImport_Import(object name)
39 # Return value: New reference.
40 # This is a higher-level interface that calls the current ``import
41 # hook function''. It invokes the __import__() function from the
42 # __builtins__ of the current globals. This means that the import
43 # is done using whatever import hooks are installed in the current
44 # environment, e.g. by rexec or ihooks.
46 object PyImport_ReloadModule(object m)
47 # Return value: New reference.
48 # Reload a module. This is best described by referring to the
49 # built-in Python function reload(), as the standard reload()
50 # function calls this function directly. Return a new reference to
51 # the reloaded module, or NULL with an exception set on failure
52 # (the module still exists in this case).
54 PyObject* PyImport_AddModule(char *name) except NULL
55 # Return value: Borrowed reference.
56 # Return the module object corresponding to a module name. The
57 # name argument may be of the form package.module. First check the
58 # modules dictionary if there's one there, and if not, create a
59 # new one and insert it in the modules dictionary. Return NULL
60 # with an exception set on failure. Note: This function does not
61 # load or import the module; if the module wasn't already loaded,
62 # you will get an empty module object. Use PyImport_ImportModule()
63 # or one of its variants to import a module. Package structures
64 # implied by a dotted name for name are not created if not already
67 object PyImport_ExecCodeModule(char *name, object co)
68 # Return value: New reference.
69 # Given a module name (possibly of the form package.module) and a
70 # code object read from a Python bytecode file or obtained from
71 # the built-in function compile(), load the module. Return a new
72 # reference to the module object, or NULL with an exception set if
73 # an error occurred. Name is removed from sys.modules in error
74 # cases, and even if name was already in sys.modules on entry to
75 # PyImport_ExecCodeModule(). Leaving incompletely initialized
76 # modules in sys.modules is dangerous, as imports of such modules
77 # have no way to know that the module object is an unknown (and
78 # probably damaged with respect to the module author's intents)
80 # This function will reload the module if it was already
81 # imported. See PyImport_ReloadModule() for the intended way to
83 # If name points to a dotted name of the form package.module, any
84 # package structures not already created will still not be
88 long PyImport_GetMagicNumber()
89 # Return the magic number for Python bytecode files (a.k.a. .pyc
90 # and .pyo files). The magic number should be present in the first
91 # four bytes of the bytecode file, in little-endian byte order.
93 PyObject* PyImport_GetModuleDict() except NULL
94 # Return value: Borrowed reference.
95 # Return the dictionary used for the module administration
96 # (a.k.a. sys.modules). Note that this is a per-interpreter
100 int PyImport_ImportFrozenModule(char *name) except -1
101 # Load a frozen module named name. Return 1 for success, 0 if the
102 # module is not found, and -1 with an exception set if the
103 # initialization failed. To access the imported module on a
104 # successful load, use PyImport_ImportModule(). (Note the misnomer
105 # -- this function would reload the module if it was already
109 int PyImport_ExtendInittab(_inittab *newtab) except -1
110 # Add a collection of modules to the table of built-in
111 # modules. The newtab array must end with a sentinel entry which
112 # contains NULL for the name field; failure to provide the
113 # sentinel value can result in a memory fault. Returns 0 on
114 # success or -1 if insufficient memory could be allocated to
115 # extend the internal table. In the event of failure, no modules
116 # are added to the internal table. This should be called before
