given:
UInt16 x = -1;
Int16 y = -1;
The value stored is exactly the same in both cases, but x will appear to be
65535 and y will appear to be -1.
There is actually nothing wrong with saying the function returns -1 (which
if unsigned is == 65535) if the resource is not found, except that it may be
confusing. When testing the return value of DmFindResource, it won't hurt
to do
if ( (Int16)result == -1 ) ...
but I don't think it is necessary. (Of course, some compilers may behave
differently.)
