Chapter 3 LoweLevel WD_xxx Interrupt Functions

This chapter describes low-level WD_xxx PCI/PCMCIA/ISA WinDriver functions.


	It is recommended to use the API from WinDriver's WDC library, which provides convenient wrappers to the basic `WD_xxx` PCI/PCMCIA/ISA API (see the WinDriver PCI Manual). If you decide not to use the WDC API, consider using the high-level `InterruptEnable` [2.18] and `InterruptDisable` [2.19] functions instead of directly using the low-level functions described below.

3.1 WinDriver Low-Level Interrupt Calling Sequence

The following is a typical calling sequence of the WinDriver API, used for servicing interrupts. The InterruptEnable and InterruptDisable functions enable interrupt handling in a more convenient manner.
