BufPciGetIrqStatus
Function Inputs the interrupt request status of the BUF-PCI(PCI) board.
Format (C)
HANDLE
hDevice ;
WORD wIrqStatus ;
WORD wIrqReset ;
DWORD dwRet ;
dwRet = BufPciGetIrqStatus( hDevice, &wIrqStatus, wIrqReset );
(Visual Basic)
Dim
hDevice As Long
Dim wIrqStatus As Integer
Dim wIrqReset As Integer
Dim dwRet As Long
dwRet = BufPciGetIrqStatus( hDevice, wIrqStatus, wIrqReset )
Argument hDevice : Specify the device handle.
Acquire this device handle with BufPciOpen.
wIrqStatus : Specify the area to store the interrupt request
status by passing its pointer.
The bit corresponding to the interrupt request (an
interrupt request level in the FA-PAC) being set to
1 indicates that an interrupt request has been
generated for that request.
wIrqReset : Specify the interrupt request to be reset. When
the bit corresponding to the interrupt request is set
to 1, that request is reset and, until the next
interrupt request comes in, the interrupt request
status bit is returned with 0 set.
Return value dwRet : Termination information
Normal termination :
0
Error : other than 0
(For more information, see the section, "List of
Return Values.")
Supplement After implementing the termination process, each function of the
BUF-PCI driver software cannot be run until reinitialized.
