``windows.winproxy`` -- Windows API
|
|
***********************************
|
|
|
|
.. module:: windows.winproxy
|
|
|
|
:mod:`windows.winproxy` tries to be a pythontic wrapper around windows API of various DLL.
|
|
It also heavily relies on :mod:`ctypes` and :mod:`windows.generated_def.winfuncs`
|
|
|
|
Here are the things to know about :mod:`windows.winproxy`
|
|
* All of this is based on :mod:`windows.generated_def.winfuncs`
|
|
* DLL is loaded the first time an API of it is called
|
|
* All parameters can be passed by ordinal or keyword
|
|
* The call will fail if an argument with default value ``NeededParamater`` have been called without another value.
|
|
* The call will raise a subclass of :class:`WindowsError` if it fails.
|
|
* Some functions are 'transparent proxy' it means that all parameters are mandatory
|
|
|
|
Example: ``VirtualAlloc``
