:mod:`MacOS` --- Access to Mac OS interpreter features
======================================================
.. module:: MacOS
:platform: Mac
:synopsis: Access to Mac OS-specific interpreter features.
:deprecated:
This module provides access to MacOS specific functionality in the Python
interpreter, such as how the interpreter eventloop functions and the like. Use
with care.
.. note::
This module has been removed in Python 3.x.
Note the capitalization of the module name; this is a historical artifact.
.. data:: runtimemodel
Always ``'macho'``, from Python 2.4 on. In earlier versions of Python the value
could also be ``'ppc'`` for the classic Mac OS 8 runtime model or ``'carbon'``
for the Mac OS 9 runtime model.
.. data:: linkmodel
The way the interpreter has been linked. As extension modules may be
incompatible between linking models, packages could use this information to give
more decent error messages. The value is one of ``'static'`` for a statically
linked Python, ``'framework'`` for Python in a Mac OS X framework, ``'shared'``
for Python in a standard Unix shared library. Older Pythons could also have the
value ``'cfm'`` for Mac OS 9-compatible Python.
.. exception:: Error
.. index:: module: macerrors
This exception is raised on MacOS generated errors, either from functions in
this module or from other mac-specific modules like the toolbox interfaces. The
arguments are the integer error code (the :cdata:`OSErr` value) and a textual
description of the error code. Symbolic names for all known error codes are
defined in the standard module :mod:`macerrors`.
.. function:: GetErrorString(errno)
Return the textual description of MacOS error code *errno*.
.. function:: DebugStr(message [, object])
On Mac OS X the string is simply printed to stderr (on older Mac OS systems more
elaborate functionality was available), but it provides a convenient location to
attach a breakpoint in a low-level debugger like :program:`gdb`.
.. note::
Not available in 64-bit mode.
.. function:: SysBeep()
Ring the bell.
.. note::
Not available in 64-bit mode.
.. function:: GetTicks()
Get the number of clock ticks (1/60th of a second) since system boot.
.. function:: GetCreatorAndType(file)
Return the file creator and file type as two four-character strings. The *file*
parameter can be a pathname or an ``FSSpec`` or ``FSRef`` object.
.. note::
It is not possible to use an ``FSSpec`` in 64-bit mode.
.. function:: SetCreatorAndType(file, creator, type)
Set the file creator and file type. The *file* parameter can be a pathname or an
``FSSpec`` or ``FSRef`` object. *creator* and *type* must be four character
strings.
.. note::
It is not possible to use an ``FSSpec`` in 64-bit mode.
.. function:: openrf(name [, mode])
Open the resource fork of a file. Arguments are the same as for the built-in
function :func:`open`. The object returned has file-like semantics, but it is
not a Python file object, so there may be subtle differences.
.. function:: WMAvailable()
Checks whether the current process has access to the window manager. The method
will return ``False`` if the window manager is not available, for instance when
running on Mac OS X Server or when logged in via ssh, or when the current
interpreter is not running from a fullblown application bundle. A script runs
from an application bundle either when it has been started with
:program:`pythonw` instead of :program:`python` or when running as an applet.
.. function:: splash([resourceid])
Opens a splash screen by resource id. Use resourceid ``0`` to close
the splash screen.
.. note::
Not available in 64-bit mode.
