Safe and unsafe are used for different meanings between languages (e.g.
C#) and the framework base class library.
In this case, like many times it's used in the FX BCL, the Unsafe prefix
means that special security requirements for this method makes it
dangerous to use with non fully-trusted code (see MSDN documentation for
So unless you are using "mono --security" to activate the (partial and
unsupported) security manager this *doesn't* affect you at all (as all
your code is *always* executed under FullTrust).
