- PCMCIA is supported only on Windows 2000/XP/Server 2003/Vista.
- Memory addresses can be accessed directly, using the user-mode
mapping of the address returned by WD_CardRegister() [2.8] (or the kernel mapping, when accessing memory
from the Kernel PlugIn).
Direct memory access is more efficient than using
WD_Transfer() [2.11].
- It is possible (although not recommended) to replace the use of
the high-level InterruptEnable() convenience function [2.18] with the low-level WD_IntEnable() [3.2], WD_IntWait() [3.3] and
WD_IntCount() [3.4] functions, and replace the call
to InterruptDisable() [2.19] with a call to the
low-level WD_IntDisable()
function [3.5].
For more information on the low-level WinDriver interrupt handling API,
refer to Chapter 3 of the manual.
- WinDriver's general-use APIs, such as WD_DebugAdd() [5.6] or WD_Sleep() [5.8], can be called
anywhere between the calls to WD_Open() and WD_Close(). For
more details, refer to Chapter 5.
