AioGetTmEvent

Function

Retrieves the event factor for window message notification relative to interval timer.

Format

Ret = AioGetTmEvent ( Id , TimerId , hWnd , TmEvent )

Parameters

Id [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Specifies the device ID retrieved from AioInit.

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

hWnd [ VB.NET : IntPtr ] [ C, C++ : HWND * ] [ C# : out IntPtr ] [ Python : ctypes.POINTER(ctypes.wintypes.HANDLE) ]
Specifies the address of the variable that stores the window handle.
If the handle needn't be retrieved, please specify NULL to it.

TmEvent [ VB.NET : Integer ] [ C, C++ : long * ] [ C# : out int ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the event factor.
TmEvent has the following meanings in bit.

Event factor	Macro	Value
Event that interval elapses	TME_INT	00000001H

Return value

Ret [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ 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.
16010	The value of TimerId is outside the designated range of the function
16011	Pointer to TmEvent is NULL Specify the address of variable to parameter.
20001	This function can't be used by this device This function cannot be used in the device without this functionality.
20002	Can not use while by another device works
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.
26010	The value of TimerId is outside the designated range of the device being used

Initial value

TmEvent = 0 for all devices

Remarks

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

Example

Retrieves the event factor of the message notification for Timer ID 0.

VB.NET	Dim Ret As Integer Dim hWnd As IntPtr Dim TmEvent As Integer Ret = AioGetTmEvent ( Id , 0 , hWnd , TmEvent )
C, C++	long Ret; HWND hWnd; long TmEvent; Ret = AioGetTmEvent ( Id , 0 , &hWnd , &TmEvent );
C#	int Ret; IntPtr hWnd; int TmEvent; Ret = aio.GetTmEvent ( Id , 0 , out hWnd , out TmEvent );
Python	Ret = ctypes.c_long() handle = ctypes.windll.user32.FindWindowW(0, "Interrupt") TmEvent = ctypes.c_long() Ret.value = caio.AioGetTmEvent ( Id , 0 , ctypes.byref(handle) , ctypes.byref(TmEvent) )
