- * Reading the file at world.path_in may put many \0-terminated strings on the

- * to and including the last \0 byte that is followed by a non-\0 byte or ends
- * the queue. If the queue starts with a \0 byte, it and its \0 followers are
- * cut and a NULL pointer is returned. Reading from the input file stops only
- * when one or more byte were read and the next read returns 0 bytes. If the
- * re-filled queue does not end in a \0 byte, a \0 byte is appended to it.
