// FUNCTION NAME: NvAPI_GetViewEx
//
// DESCRIPTION: This API lets caller retrieve the target display arrangement for selected source display handle.
//
// SUPPORTED OS: Windows Vista and higher
//
// PARAMETERS: hNvDisplay(IN) - NVIDIA Display selection. NVAPI_DEFAULT_HANDLE not allowed, it has to be a handle enumerated with NvAPI_EnumNVidiaDisplayHandle().
// pPathInfo(IN/OUT) - count field should be set to NVAPI_MAX_DISPLAY_PATH. Can be NULL to retrieve just the pathCount.
// pPathCount(IN/OUT) - Number of elements in array pPathInfo->path.
// pTargetViewMode(OUT)- Display view selected from NV_TARGET_VIEW_MODE.
//
// RETURN STATUS:
// NVAPI_OK - completed request
// NVAPI_API_NOT_INTIALIZED - NVAPI not initialized
// NVAPI_ERROR - miscellaneous error occurred
// NVAPI_INVALID_ARGUMENT - Invalid input parameter.
// NVAPI_EXPECTED_DISPLAY_HANDLE - hNvDisplay is not a valid display handle.
