Hi,
I wanted to know if there is a way to share DLL memory with Labview, (in a simple windows 2000 desktop computer). For example, if I have two C processes, (C-Process-1 and C-Process-2), attached to a DLL with a shared memory segment, each C process can read and write directly to the shared memory, (declared in the DLL, using a shared segment, and exported properly). That is, if C-Process-1 writes to DLL-shared-memory-array[100], C-Process-2 can read those values from DLL-shared-memory-array[100] directly without calling any functions to pass/copy any of the data. That is, there is no passing data between the DLL and the processes. The memory is simply shared and directly addressed by each process. This I know is true and have implemented such a strategy. I want to know if the same paradigm is possible using Labview. Could I substitute a Labview program, (call it Labview-1), for C-Process-2 in the above example and have it work the same way. That is, could I setup the system such that Labview-1 could assign values directly to DLL-shared-memory-array[100], and C-Process-1 could directly read them. And vice-versa. I know I could setup function calls to the DLL, (from Labview-1), and pass data in and out to DLL-shared-memory-array[100], but again, I don't want to pass the data. That would be wasting cpu time, (and memory), over direct mapping, (I think).
Thanks,
Nu
