def get_pywin32_module_file_attribute(module_name):
    """
    Get the absolute path of the PyWin32 DLL specific to the PyWin32 module
    with the passed name.

    On import, each PyWin32 module:

    * Imports a DLL specific to that module.
    * Overwrites the values of all module attributes with values specific to
      that DLL. This includes that module's `__file__` attribute, which then
      provides the absolute path of that DLL.

    This function safely imports that module in a PyWin32-aware subprocess and
    returns the value of that module's `__file__` attribute.

    Parameters
    ----------
    module_name : str
        Fully-qualified name of that module.

    Returns
    ----------
    str
        Absolute path of that DLL.

    See Also
    ----------
    `PyInstaller.utils.win32.winutils.import_pywin32_module()`
        For further details.
