Function

Stops the count operation.

Format

Ret = DioStopCount ( Id , ChNo , ChNum )

Parameters

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

ChNo [ C, C++: short *] [Python: ctypes.POINTER(ctypes.c_short)]
Specifies the start address of the array that stores the channel number to stop counting.

ChNum [ C, C++: short] [Python: ctypes.c_short]
Specifies the number of channels specified in ChNo.

Return Value

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

Definition	Value [Dec]	Description

DIO_ERR_DLL_CALL_DRIVER	10002	Driver cannot be called (failed in ioctl).
DIO_ERR_DLL_BUFF_ADDRESS	10100	Invalid data buffer address.
DIO_ERR_SYS_NOT_SUPPORTED	20001	This function cannot be used for this device.

Remarks

- Stops the count of the specified channels.

Example

Stops the count for Channel0 and Channel1.

C, C++

long Ret;

short ChNo[2]

ChNo[0] = 0;
ChNo[1] = 1;

Ret = DioStopCount(Id, &ChNo[0], 2);

Python

Ret = ctypes.c_long()

ChNoType = ctypes.c_short * 2
ChNo = ChNoType()

ChNo[0] = 0
ChNo[1] = 1

Ret.value = cdio.DioStopCount(Id, ChNo, 2)
