I have a C++ DLL returning an int*
to a C# program. The problem is the int*
in C# remains null
after the assignment.
When I assign the C++ result to an IntPtr
, I get a correct non-null value. However any attempt to convert this to an int*
results in null
.
I've tried:
IntPtr intp = cppFunction (); // Non-null.
int* pi = (int *) intp; // Results in null.
int* pi = (int *) intp.ToPointer (); // Results in null.
void* vp = intp.ToPointer ();
int* pi = (int *) vp; // Results in null, but vp is non-null.
How can I get a non-null int*
?
Thanks! Alan
