# STRING
STRING provides a way to allocate and free text strings, while de-duplicating them.
It can be used similarly to libc string functions:
- `strdup()` and `strdupz()` become `string_strdupz()`.
- `strlen()` becomes `string_strlen()` (and it does not walkthrough the bytes of the string).
- `free()` and `freez()` become `string_freez()`.
There is also a special `string_dup()` function that increases the reference counter of a STRING, avoiding the
index lookup to find it.
Once there is a `STRING *`, the actual `const char *` can be accessed with `string2str()`.
All STRING should be constant. Changing the contents of a `const char *` that has been acquired by `string2str()` should never happen.
