``MacOS`` --- Access to Mac OS interpreter features
***************************************************

Platform: Mac

*Platforms: *Mac

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.

MacOS.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.

MacOS.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 exception MacOS.Error

   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 ``OSErr`` value) and a textual description of the error code.
   Symbolic names for all known error codes are defined in the
   standard module ``macerrors``.

MacOS.GetErrorString(errno)

   Return the textual description of MacOS error code *errno*.

MacOS.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 **gdb**.

   Note: Not available in 64-bit mode.

MacOS.SysBeep()

   Ring the bell.

   Note: Not available in 64-bit mode.

MacOS.GetTicks()

   Get the number of clock ticks (1/60th of a second) since system
   boot.

MacOS.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.

MacOS.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.

MacOS.openrf(name[, mode])

   Open the resource fork of a file. Arguments are the same as for the
   built-in function ``open()``. The object returned has file-like
   semantics, but it is not a Python file object, so there may be
   subtle differences.

MacOS.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 **pythonw**
   instead of **python** or when running  as an applet.

MacOS.splash([resourceid])

   Opens a splash screen by resource id. Use resourceid ``0`` to close
   the splash screen.

   Note: Not available in 64-bit mode.
