And how to understand the following code, I can't understand, what's the use of some parameters in the parentheses lib Alias represents what
Private Declare Sub CopyMemory _
Lib "KERNEL32" _
Alias "RtlMoveMemory" (hpvDest As Any, _
ByVal hpvSource As Long, _
ByVal cbCopy As Long)

Said is behind the KERNEL32. The function in the DLL RtlMoveMemory (formerly), but you can declare for different function name, in a program called CopyMemory (this is actually an alias),
