First of all, "this code is not working" is a bit generic...
Second, you can evaluate tools like Onboard resource editor to inspect the
contents of pdb on POSE (or real palm devices).

why do you use the pointer to x->name if x->name is already the pointer to
the string that you need?
Why not:
DmStrCopy(p, offset, x->name);
