You can't. You can mark the @safe function @trusted [1] instead.
@trusted functions are considered memory-safe by the compiler and can be
called from @safe code, but they can use @system features and call
@system functions.
A @trusted function must still be memory-safe, and the compiler cannot
check that it is, so you as the programmer take on the responsibility to
ensure that the function is in fact memory-safe.
Be very careful with @trusted and make sure you know exactly what you're
doing. A bad @trusted function compromises the whole call chain.
