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. [1] https://dlang.org/spec/function.html#trusted-functions
