### C types
Ordinary zero terminated C strings can be converted to V strings with
`unsafe { charptr(cstring).vstring() }` or if you know their length already with
`unsafe { charptr(cstring).vstring_with_len(len) }`.
`unsafe { &char(cstring).vstring() }` or if you know their length already with
`unsafe { &char(cstring).vstring_with_len(len) }`.
NB: The .vstring() and .vstring_with_len() methods do NOT create a copy of the `cstring`,
so you should NOT free it after calling the method `.vstring()`.
@ -3594,9 +3594,9 @@ These can be converted to V strings with `string_from_wide(&u16(cwidestring))` .
V has these types for easier interoperability with C:
- `voidptr` for C's `void*`,
- `byteptr` for C's `byte*` and
- `charptr` for C's `char*`.
- `&charptr` for C's `char**`
- `&byte` for C's `byte*` and
- `&char` for C's `char*`.
- `&&char` for C's `char**`
To cast a `voidptr` to a V reference, use `user := &User(user_void_ptr)`.
