AioLapTmCount


Function

Retrieves the current elapsed time.

Format

Ret = AioLapTmCount ( Id , TimerId , Lap)

Parameters

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

TimerId [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the timer ID.

Lap [ C, C++ : long * ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the elapsed time.
The elapsed time is in the unit of "msec".

Return values

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

Return values

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.

16120

The value of TimerId is outside the designated range of the function

16121

Pointer to Lap is NULL
Specify the address of variable to parameter.

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.

26120

The value of TimerId is outside the designated range of the device being used

Remarks

Starts the measurement of elapsed time. Because the measurement doesn't stop, you can perform it again and again.
This function cannot be used on devices without timer functionality.

Example

Retrieves the current elapsed time for timer ID 0.

C, C++

long Ret;
long Lap;
Ret = AioLapTmCount ( Id , 0 , &Lap );
 

Python

Ret = ctypes.c_long()
Lap = ctypes.c_long()
Ret.value = caio.AioLapTmCount ( Id , 0 , ctypes.byref(Lap) )
