Detailed Description

Function Documentation

_INT_ i_PCI3200_SetBoardIntRoutine ( HANDLE  h_DeviceHandle,
void(*)(HANDLEh_DeviceHandle, BYTEb_FIFOOverflow, DWORDdw_InterruptSource, DWORDdw_InterruptMask, DOUBLE *pd_Args, DWORDdw_ArgsCount)  v_FunctionName 
)

Install an interrupt callback function. This function will be called each time the board generate an interrupt.

Parameters
[in]h_DeviceHandle: Handle of the board
[in]v_FunctionName: Address of the callback function
h_DeviceHandle : Handle of the board
b_FIFOOverflow : If uc_FIFOOverflow != 0, there are too many untreated interrupts in the kernel FIFO, and any new information is lost
dw_InterruptSource : Source of the interrupt. Contains the module which generated the interrupt (0,1,2 or 3)
dw_InterruptMask : Ground of the interrupt (0x1 means the scan conversion is available)
pd_Args : Values read during the interrupt. If the dw_InterruptMask is 0x1, the array contains the measured temperature (in Celcius)
dw_ArgsCount : Number of values read during the interrupt
Return values
0: No Error
-1: The device handle parameter is wrong
-2: An interrupt routine was still installed. Remove it with i_PCI3200_ResetBoardIntRoutine and retry
-3: Error while creating kill event
-4: Error while creating interrupt event
-5: Error while creating interrupt thread
-6: Error while changing the priority class of the thread
-7: Error while changing the priority of the thread
-8: Error while calling the IOCTL command
-9: Error in the interrupt callback function
_INT_ i_PCI3200_ResetBoardIntRoutine ( HANDLE  h_DeviceHandle)

Deinstall the interrupt callback function.

Parameters
[in]h_DeviceHandle: Handle of the board
Return values
0: No Error
-1: The device handle parameter is wrong
-2: No interrupt routine installed
-3: Error in the reset interrupt callback function
