:mod:`MacOS` --- Access to Mac OS interpreter features
|
|
======================================================
|
|
|
|
.. module:: MacOS
|
|
:platform: Mac
|
|
:synopsis: Access to Mac OS-specific interpreter features.
|
|
|
|
|
|
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 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`.
|
|
|
|
|
|
.. function:: SysBeep()
|
|
|
|
Ring the bell.
|
|
|
|
|
|
.. 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.
|
|
|
|
|
|
.. 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.
|
|
|
|
|
|
.. 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.
