Without going into detail, the unsafe keyword does a lot more than that.
"Unsafe C#" (more often referred to as unmanaged code) is analogous to
Java's JNI.
It allows the use of pointers, etc. and has the intention of allowing
existing C/C++ users to migrate over to C# i.e. run C/C++ native code from
C#.
The /unsafe compiler switch says "I know that this code does its own memory
management (etc.) and doesn't fit into the typical .NET model, but I'm
willing to accept that".
