Pointer to LabVIEW Array

LabVIEW memory management question:

Question Part 1: When I write a C .dll that takes a LabVIEW array,
LabVIEW passes a pointer into LabVIEW's memory to the array to C. 
Can C return the pointer to me (e.g., not the array I passed in, but
it's memory location)?

i.e.: void GetNativeMemoryPointer(float *pointer, float *array);

where *array is my input array, and GetNativeMemoryPointer returns the pointer to this array on *pointer.

Question Part 2: What issues will I run in to if I pass this returned
pointer to another .dll call.  What if this .dll call is in
NET? 

Concerns: How does LabVIEW hold this array in memory?  When I call
GetNativeMemoryPointer, does LabVIEW make a copy and send this a
pointer to the copy to the dll, or is the pointer to the
original?  Will LabVIEW ever "move" the original, e.g., will my
pointer become invalid after some time?
.
