QString is a high-level data type that can be used to represent C strings. The following functions are available: - qstring_from_str() Create a new QString - qstring_get_str() Get a pointer to the stored string Note that qstring_get_str() is too low-level for a data type like this, but it's interesting for quick read-only accesses.
