a gsize to get the length of the data read in

GException on failure.
2.26
Reads a string from the data input stream, up to the first occurrence of any of the stop characters.
In contrast to DataInputStream.readUntil, this function does not consume the stop character. You have to use DataInputStream.readByte to get it before calling DataInputStream.readUpto again.
Note that stop_chars may contain '\0' if stop_chars_len is specified.
The returned string will always be nul-terminated on success.
