pub unsafe extern "C" fn CSTL_u8string_c_str(
instance: CSTL_UTF8StringCRef,
) -> *const char8_tExpand description
Returns a const pointer to the underlying null-terminated array serving as character storage.
If CSTL_u8string_empty(instance) == true the pointer is still
valid and points to a single null character.
The range [CSTL_u8string_c_str(instance), CSTL_u8string_c_str(instance) + size]
is always valid.
