i
IMPORTANT!
This function can only be used for C/C++ and Pascal for DOS b
Syntax:
<Return-Wert> = i_APCI1710_SetBoardIntRoutineDos
(BYTE
b_BoardHandle,
VOID v_FunctionName
(BYTE b_BoardHandle,
BYTE b_ModuleMask,
ULONG ul_InterruptMask,
ULONG ul_CounterLatchValue))
Parameter:
- Input:
BYTE b_BoardHandle Handle der xPCI-1710 Karte
VOID v_FunctionName Name der Benutzer-Interruptroutine
- Output:
No output signal.
Task:
This function is to be called for all xPCI-1710 board on which you want to
activate an interrupt.
At the first calling function (first board):
- the user interrupt routine is installed
- interrupts are made possible
If you operate various xPCI-1710 boards that shall react to interrupts, you
shall call the function as many times as how many xPCI-1710 boards you
are operating.
The variable
v_FunctionName
is only important at the first calling. From the
second calling of the function on (next boards), interrupts are enabled.
Interrupt
If an interrupt is generated, the user interrupt routine is called up by the
system. If various boards are operated and shall react to interrupts, the
variable
b_BoardHandle
shows the identification number (handle) of the
board, which has generated the interrupt.
The user interrupt routine must have the following syntax:
VOID_ v_FunctionName (BYTE
b_BoardHandle,
BYTE b_ModuleMask
ULONG ul_InterruptMask,
ULONG ul_CounterLatchValue)
