WDC_ReadAddrBlock()

DWORD DLLCALLCONV WDC_ReadAddrBlock	(	_In_ WDC_DEVICE_HANDLE	hDev,
		_In_ DWORD	dwAddrSpace,
		_In_ KPTR	dwOffset,
		_In_ DWORD	dwBytes,
		_Outptr_ PVOID	pData,
		_In_ WDC_ADDR_MODE	mode,
		_In_ WDC_ADDR_RW_OPTIONS	options
	)

Reads a block of data from the device.

Parameters

[in]	hDev	Handle to a WDC device, returned by WDC_xxxDeviceOpen()
[in]	dwAddrSpace	The memory or I/O address space to read from
[in]	dwOffset	The offset from the beginning of the specified address space (dwAddrSpace) to read from
[in]	dwBytes	The number of bytes to read
[out]	pData	Pointer to a buffer to be filled with the data that is read from the device
[in]	mode	The read access mode -see WDC_ADDR_MODE
[in]	options	A bit mask that determines how the data will be read see WDC_ADDR_RW_OPTIONS. The function automatically sets the WDC_RW_BLOCK flag.

Returns

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