How can i call @system function in a @safe function?
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.
