object PyImport_ImportModule(const char *name)
|
|
# Return value: New reference.
|
|
# This is a simplified interface to PyImport_ImportModuleEx()
|
|
# below, leaving the globals and locals arguments set to
|
|
# NULL. When the name argument contains a dot (when it specifies a
|
|
# submodule of a package), the fromlist argument is set to the
|
|
# list ['*'] so that the return value is the named module rather
|
|
# than the top-level package containing it as would otherwise be
|
|
# the case. (Unfortunately, this has an additional side effect
|
|
# when name in fact specifies a subpackage instead of a submodule:
|
|
# the submodules specified in the package's __all__ variable are
|
|
# loaded.) Return a new reference to the imported module, or NULL
|
|
# with an exception set on failure.
|
|
|
|
object PyImport_ImportModuleEx(const char *name, object globals, object locals, object fromlist)
|
|
# Return value: New reference.
|
|
|
|
# Import a module. This is best described by referring to the
|
|
# built-in Python function __import__(), as the standard
|
|
# __import__() function calls this function directly.
|
|
|
|
# The return value is a new reference to the imported module or
|
|
# top-level package, or NULL with an exception set on failure
|
|
# (before Python 2.4, the module may still be created in this
|
|
# case). Like for __import__(), the return value when a submodule
|
|
# of a package was requested is normally the top-level package,
|
|
# unless a non-empty fromlist was given. Changed in version 2.4:
|
|
# failing imports remove incomplete module objects.
|
|
|
|
object PyImport_ImportModuleLevel(char *name, object globals, object locals, object fromlist, int level)
|
|
# Return value: New reference.
|
|
|
|
# Import a module. This is best described by referring to the
|
|
# built-in Python function __import__(), as the standard
|
|
# __import__() function calls this function directly.

# The return value is a new reference to the imported module or

|
object PyImport_Import(object name)
|
|
# Return value: New reference.
|
|
# This is a higher-level interface that calls the current ``import
|
|
# hook function''. It invokes the __import__() function from the
|
|
# __builtins__ of the current globals. This means that the import
|
|
# is done using whatever import hooks are installed in the current
|
|
# environment, e.g. by rexec or ihooks.
|
|
|
|
object PyImport_ReloadModule(object m)
|
|
# Return value: New reference.
|
|
# Reload a module. This is best described by referring to the
|
|
# built-in Python function reload(), as the standard reload()
|
|
# function calls this function directly. Return a new reference to
|
|
# the reloaded module, or NULL with an exception set on failure
|
|
# (the module still exists in this case).
|
|
|
|
PyObject* PyImport_AddModule(const char *name) except NULL
|
|
# Return value: Borrowed reference.
|
|
# Return the module object corresponding to a module name. The
|
|
# name argument may be of the form package.module. First check the
|
|
# modules dictionary if there's one there, and if not, create a
|
|
# new one and insert it in the modules dictionary. Return NULL
|
|
# with an exception set on failure. Note: This function does not
|
|
# load or import the module; if the module wasn't already loaded,
|
|
# you will get an empty module object. Use PyImport_ImportModule()
|
|
# or one of its variants to import a module. Package structures
|
|
# implied by a dotted name for name are not created if not already
|
|
# present.
|
|
|
|
object PyImport_ExecCodeModule(char *name, object co)
|
|
# Return value: New reference.
|
|
# Given a module name (possibly of the form package.module) and a
|
|
# code object read from a Python bytecode file or obtained from
|
|
# the built-in function compile(), load the module. Return a new
|
|
# reference to the module object, or NULL with an exception set if
|
|
# an error occurred. Name is removed from sys.modules in error
|
|
# cases, and even if name was already in sys.modules on entry to
|
|
# PyImport_ExecCodeModule(). Leaving incompletely initialized
|
|
# modules in sys.modules is dangerous, as imports of such modules
|
|
# have no way to know that the module object is an unknown (and
|
|
# probably damaged with respect to the module author's intents)
|
|
# state.
|
|
# This function will reload the module if it was already
|
|
# imported. See PyImport_ReloadModule() for the intended way to
|
|
# reload a module.
|
|
# If name points to a dotted name of the form package.module, any
|
|
# package structures not already created will still not be
|
|
# created.
|
|
|
|
|
|
long PyImport_GetMagicNumber()
|
|
# Return the magic number for Python bytecode files (a.k.a. .pyc
|
|
# and .pyo files). The magic number should be present in the first
|
|
# four bytes of the bytecode file, in little-endian byte order.
|
|
|
|
PyObject* PyImport_GetModuleDict() except NULL
|
|
# Return value: Borrowed reference.

# Return the dictionary used for the module administration
|
|
# (a.k.a. sys.modules). Note that this is a per-interpreter
|
|
# variable.
|
|
|
|
|
|
int PyImport_ImportFrozenModule(char *name) except -1
|
|
# Load a frozen module named name. Return 1 for success, 0 if the
|
|
# module is not found, and -1 with an exception set if the
|
|
# initialization failed. To access the imported module on a
|
|
# successful load, use PyImport_ImportModule(). (Note the misnomer
|
|
# -- this function would reload the module if it was already
|
|
# imported.)
|
|
|
|
|
|
int PyImport_ExtendInittab(_inittab *newtab) except -1
|
|
# Add a collection of modules to the table of built-in
|
|
# modules. The newtab array must end with a sentinel entry which
|
|
# contains NULL for the name field; failure to provide the
|
|
# sentinel value can result in a memory fault. Returns 0 on
|
|
# success or -1 if insufficient memory could be allocated to
|
|
# extend the internal table. In the event of failure, no modules
|
|
# are added to the internal table. This should be called before
|
|
# Py_Initialize().
