AioResetCntStatus

Function

Resets the counter status.

Format

Ret = AioResetCntStatus ( Id , CntChannel , CntStatus )

Parameters

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

CntChannel [ C, C++ : short ] [ Python : ctypes.c_short ]
Sets the channel of counter.

CntStatus [ C, C++ : long ] [ Python : ctypes.c_long ]
Specifies the status to reset from the following range in macro or numerical value.
CntStatus has the following meanings in bit, it can be specified by a combination of these bits.

Status	Macro	Value
Comparison count match	CNTS_DATA_NUM	00000010H
Overrun	CNTS_ORERR	00010000H

Return values

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

Return values	Content
0	Normality completion
7	Execute AioResetDevice function because the device has recovered from standby mode
10001	Invalid Id was specified Use the Id retrieved from AioInit to specify the Id in this function.
10002	AIO driver can't be called At first, perform AioInit function.
15240	The value of CntChannel is outside the designated range of the function
20001	This function can't be used by this device
20003	Can not use because another process is using the device When another process is using the device, all functions except for those that support multi-process can not be performed.
25240	The value of CntChannel is outside the designated range of the device being used

Remarks

This function cannot be used on devices without counter functionality.
Even if the device is in operation, the function can be performed.

Example

Resets the counter status for channel 0.

C, C++	long Ret; Ret = AioResetCntStatus ( Id , 0 , CNTS_DATA_NUM \| CNTS_ORERR );
Python	Ret = ctypes.c_long() Ret.value = caio.AioResetCntStatus ( Id , 0 , caio.CNTS_DATA_NUM \| caio.CNTS_ORERR )
