we have some questions regarding the first lab.
- Do we have to do error handling for print functions?
- Do we have to do error handling for the wait function?
- Do we have to ensure that the message queue has already been created by the parent at the time the child tries to open it?
- In Questions 3.2,4.2 and 5.2 the term "multi-threaded software" is used. Does this strictly refer to software that makes use of multiple threads or does it also include software that uses multiple processes?
