# 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.
