#define WD_PciScanCaps	(		h,
			pPciScanCaps
	)

Value:

    WD_FUNCTION(IOCTL_WD_PCI_SCAN_CAPS, h, pPciScanCaps, \
        sizeof(WD_PCI_SCAN_CAPS), FALSE)

Scans the specified PCI capabilities group of the given PCI slot for the specified capability (or for all capabilities).

Parameters

[in]	h	Handle to WinDriver's kernel-mode driver as received from WD_Open()
[in,out]	pPciScanCaps	Pointer to a PCI capabilities scan structure

Returns

Returns WD_STATUS_SUCCESS (0) on success, or an appropriate error code otherwise
