Purpose
• A convenient function for shutting down interrupt handling.
Prototype
DWORD InterruptDisable(HANDLE hThread);
Parameters
Description
Return Value
Returns WD_STATUS_SUCCESS (0) on success, or an appropriate
error code otherwise [A].
Remarks
-
You can view the implementation of this function in
WinDriver/src/wdapi/windrvr_int_thread.c.
InterruptDisable() uses the low-level
WD_IntDisable() [3.5]
function. When using InterruptEnable() [2.18] to enable interrupts, instead of calling the
low-level WD_IntEnable() [3.2], WD_IntWait() [3.3] and WD_IntCount() [3.4] functions separately, the interrupts should be
disabled using InterruptDisable() and not
WD_IntDisable()
Example
main()
{
....
if (InterruptEnable(&thread_handle, hWD, &Intrp,
interrupt_handler, pData))
{
printf("failed enabling interrupt\n");
}
else
{
printf("Press Enter to uninstall interrupt\n");
fgets(line, sizeof(line), stdin);
InterruptDisable(thread_handle); /* Calls WD_IntDisable() */
}
....
}
