Hm...
MemHandleLock returns VoidPtr.
I assume that RecPointer is CharPtr, so you should explicitly cast the
result:
RecPointer = (CharPtr)MemHandleLock(RecHandle);
name[i] = RecPointer[i+offset];
if(RecPointer[i+2] == '\n') {
If I do remember that correctly, void pointers cannot be casted
implicitly to non-void in C, whereas vice versa is allowed.
