scanf from stdio.h can be in Rust with fk_std for FOMOS development or FOMOS app and command development. In C when you
call scanf it would be something like this:

    #include <stdio.h>

    char input[100];
    scanf("%s", input);

In fk_std when you call scanf you would do something like this:

    use fk_std::{c_char, scanf};

    const INPUT: &'static str = "User input";
    unsafe { scanf(INPUT.as_ptr(), as *const c_char); }
