TLB file compiled

I have an TLB file got compiled into VC++ code but fails at
one line

void __stdcall CopyMemory(void* Dest, void* Src, long len);

Errors are

error C2146: syntax error: missing ) before identifier 'Dest'
error C2065: Dest: undeclared identifier
warning C4229: anachism used: modifers on data are ignored
error C2182: memcpy: illegal used of type void
error C2059: syntax error )

Any helpful replies are appreciated. Thanks :( :(
