Function ruby_strdup 

pub unsafe extern "C" fn ruby_strdup(
    str_: *const c_char,
) -> *mut c_char

This is our own version of strdup(3) that uses ruby_xmalloc() instead of system malloc (benefits our GC).

@param[in] str Target C string to duplicate. @return An allocated C string holding the identical contents. @note Return value must be discarded using ruby_xfree().
