Low Level API

Windows programs can use HyCNC-4P to generate motion and other control

signals via API functions. API consists of HyCNC_4P.LIB and its header file

HyCNC_4P.H. The latest API can be downloaded from

http://www.hytechworks.com/Downloads/HyCnc/HyCNC_4P/index_c.html

The API has following functions.

Device Identification and Opening

BOOL HyCNC_GetDevicePathByGUID(LPGUID DeviceGuid, char *DevicePath, DWORD

DeviceIndex)

HyCncLib_GetDevicePathByGUID identifys the path of a HyCNC-4P interface by its

driver GUID.

DeviceGuid – pointer to the device GUID.

DevicePath – pointer to store the device path string found according to the GUID

and device index.

DeviceIndex – index to the number of the device in system list, starting with 0.

If the function succeeds, the return value is true. Otherwise, it returns false.

HANDLE HyCNC_OpenDeviceByPath(char *DevicePath)

HyCncLib_OpenDeviceByPath opens HyCNC-4P interface by its path obtained

from calling HyCncLib_GetDevicePathByGUID.

DevicePath – pointer to the device path string.

If the function returns the device handle. If it fails, the handle is

INVALID_HANDLE_VALUE.
