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

Name	Type	Input/Output
$\bullet$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
$\gg$kpCall	WD_KERNEL_PLUGIN_CALL	N/A
$\gg$fEnableOk	DWORD	N/A
$\gg$dwCounter	DWORD	Output
$\gg$dwLost	DWORD	Output
$\gg$fStopped	DWORD	Output

DESCRIPTION

Name	Description
hWD	The handle to WinDriver's kernel-mode driver received from WD_Open() [5.2]
pInterrupt	Pointer to an interrupt information structure:
hInterrupt	Handle of interrupt, returned by WD_CardRegister() [2.8] in I.Int.hInterrupt.
dwCounter	Number of interrupts received
dwLost	Number of interrupts not yet handled
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;
