APCI-1710
Shared memory:
If you have chosen the APCI1710_Synchronous_Mode, you have no access
to the common function. However, you have the possibility to create a
shared memory (ppv_UserSharedMemory), in which all given compilers or
user defines are saved.
The variable ul_UserSharedMemorySize identifies the size in byte of the
selected user type.
An indicator of the variable pv_UserSharedMemory will be returned to the
interrupt routine with the variable pv_ USerSharedMemory. This function is
not possible in Visual Basic.
The user interrupt routine shall have the following syntax:
VOID v_FunctionName
v_FunctionName
b_BoardHandle
b_ModuleMask
ul_InterruptMask
ul_CounterLatchValue
b_UserCallingMode
pv_UserSharedMemory
The user can use other names for v_FunctionName, b_BoardHandle,
b_ModuleMask, ul_InterruptMask, ul_CounterLatchValue,
b_UserCallingMode und pv_UserSharedMemory.
IMPORTANT!
i
If you use Visual Basic 4 the following parameters have no
meaning. Use the function: "i_APCI1710_TestInterrupt".

Handle of the APCI-1710, which has
generated the interrupt.
Mask of the module, which has
generated the interrupt

the interrupt

The latched values of the counter are
returned.

APCI1710_SYNCHRONOUS_MODE:
The user routine is called directly from
the driver interrupt routine
APCI1710_ASYNCHRONOUS_MODE:
The user interrupt routine is called
directly from the driver interrupt thread.
