Hello. How to use @safe when a C library integration needed?
Everything need a system function...
```d
@safe fn()
{
// lot of safe stuff
() @trusted {
// in this block[*] @system function like extern C can be
called.
// you need to make sure the API is used correct
@assert(/*C_Fun is safe to be used with param1*/);
@assert(/*C_Fun is safe to be used with param2*/);
C_Fun(param1, param2);
}();
// more safe stuff
}
```
[*] in fact, this is a lambda function that is directly called,
because real trusted blocks are not allowed (yet).
