3.4 WD_IntCount()

PURPOSE

$\bullet$Retrieves the interrupts count since the call to WD_IntEnable() [3.2].

PROTOTYPE

void WD_IntCount(
    HANDLE hWD,
    WD_INTERRUPT *pInterrupt);

PARAMETERS

$\bullet$hWD	HANDLE	Input
$\bullet$pInterrupt	WD_INTERRUPT*
$\gg$hInterrupt	HANDLE	Input
$\gg$dwOptions	DWORD	N/A
$\gg$Cmd	WD_TRANSFER*	N/A
$\gg$dwCmds	DWORD	N/A

DESCRIPTION

Name	Description
hWD	Handle to WinDriver's kernel-mode driver as received from WD_Open() [5.2]
pInterrupt	Pointer to an interrupt information structure:
$\bullet$ hInterrupt	Handle of interrupt, returned by WD_CardRegister() [2.8] in I.Int.hInterrupt.
$\bullet$ dwCounter	Number of interrupts received
$\bullet$ dwLost	Number of interrupts not yet handled
$\bullet$ fStopped	Set by the function to TRUE if interrupt was disabled while waiting for interrupts

RETURN VALUE

Returns WD_STATUS_SUCCESS (0) on success, or an appropriate error code otherwise [A].

EXAMPLE

DWORD dwNumInterrupts;

WD_IntCount(hWD, &Intrp);
dwNumInterrupts = Intrp.dwCounter;
