How to get the memory address of an array (pointer in C)?

[antneewills]

I am writing an application that exchanges data with a PXI device via DMA.  Basically I will provide it a memory address and a direction, and it transfers the data.  I would like to give it the memory location of an array in LabVIEW, but I do not know how to get the memory location without doing a DLL call to C code that returns the pointer.  Is there an easy way to do this in LabVIEW?  Any help is much appreciated.

A similar question was asked recently regarding strings. You cannot pass pointers in LabVIEW as you do in C. You can pass an array to a DLL, but that means you would need to write a wrapper DLL. Be sure to read the section in the LabVIEW Help on calling code from text-based languages and also take a look at the "Call DLL" example that ships with LabVIEW  - it contains many examples of how to deal with various datatypes.
