Just some more info, here's how a demonstration C program looks:

00006 int CheckError(ASX_HANDLE hObj, int nLine);
00007
00008 ASX_HANDLE hSystem=0;
00009
00010 int main(int argc, char* argv[])
00011 {
00012
00013 ASX_ERROR asxError;
00014 int nAdapters=0;
00015 int i;
00016
00017 // create the system
00018 ASX_System_Create(ASX_SYSTEM_TYPE_HPI,&hSystem);


I'm not sure what line 8 is doing and how that works with the call in line 18.
