Function

Specifies the callback function called when the event of sampling stopping occurs.

Format

Ret = CntSetSamplingStopEvent ( Id , CallBackProc, Param )

Parameters

Id [C: short] [Python: ctypes.c_short]
Specifies the device ID retrieved from CntInit.

CallBack [C: PCNT_SAMPLING_STOP_CALLBACK] [Python: PCNT_SAMPLING_STOP_CALLBACK]
Specifies the address of callback function.

Param [C: void *] [Python: ctypes.c_void_p]
Specifies the parameter passed to the callback function.

Return Value

Ret [C: long] [Python: ctypes.c_long]

Definition	Value	Description

Remarks

It is the function which accept the interrupt by using the sampling stop interrupt function of hardware.
After setting the interrupt callback setting, sets the interrupt event,
the callback function is called when the interrupt occurs.

For Ethernet devices
  If communication with the device is lost, the process will be unregistered and events will no longer be notified.
  If you want to perform event notification again, please make the settings again using this function.

  You can check the registration status of the current process using the CntGetNetCommunicationInfo function.

Example

C	Ret = CntSetSamplingStopEvent ( Id , CallBackProc, Param );
Python	Ret = ccnt.CntSetSamplingStopEvent ( Id , CallBackProc, Param )
