Subject:Re: [jna-users] Getting pointer from pointerActions...

Pointer memcpy(Pointer, Pointer, int); Pointer memcpy(Pointer, Pointer, long);

long size = ...; if (Pointer.SIZE == 4) memcpy(p1, p2, (int)size); else memcpy(p1, p2, size);

If you're using traditional JNA interface mapping, you can define a size_t IntegerType which has the appropriate size based on pointer sizes (the source for Structure has just such an implementation for internal use).

Hi.

There is no Java size_t type. With 3.1.0 you'd need to define two signatures and choose one based on the size of size_t.

Any example how to do it?
