![]() ![]() I use this when using a plugin architecture. NATIONAL INSTRUMENTS LICENCES ACTIVATOR V1. 2 CODEThe following code will also give you an array of all of the children loaded in memory, but this time it uses less VI Server so it will work in the runtime environment. ![]() According to the documentation this will NOT work in the runtime environment, but i've used this several times when making IDE Tools. This means that once a class is loaded into memory, the parent knows about the child. It's even better to make a Conditional Disable Structure with two cases for 32-bits and 64-bits, where a pointer field would be an U32 or U64 number respectively.Ĭhildren have a static link to their parents and Parents have a dynamic link to their children. So if you are working in 32-bit LabVIEW, you should cast it to U32 explicitly before building a cluster. After the IQSTREAM_GetIQData call you likely want to extract the array data into a LabVIEW array, so before doing DSDisposePtr you would call MoveBlock to transfer the data.Īlso an important note: Unsigned Pointer-sized Integers are always represented as U64 numbers on the diagram. Of course, you may make some memory margin and it's not doing any bad, except taking an extra space in RAM. Then which representation does that array have? If there are common double values, it's enough to allocate 8*100 bytes of memory. The same for the third field: triggerIndices -> ListTI. The second field should be triggerCount, but the cluster has it named as triggerindices. I see some inconsistencies in your struct declaration and the cluster on the diagram. ![]() If the struct is very complex (not in your case) it's possible to pass a (prearranged) pointer as an Unsigned Pointer-Sized Integer and take it apart after the call with MoveBlock function. In this case LabVIEW provides a pointer to the structure (cluster). Each time a library function wants a struct pointer as an input parameter, you should pass it as Adapt to Type -> Handles by Value. ![]()
