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	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.
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) )
