In a typical operating system, User$-$Processes often have needs to direct data from buffers for printing $($on a printer$).$ Assuming that a single $$spooling$-$buffer$$ is used to queue up print requests from processes to the Printer. Set up a critical section solution to control the concurrent access to this buffer between the Printer$-$Process and all the User Processes. Assume that both types of processes use a simple binary semaphore variable, mutex, for the needed synchronization, and any other type of semaphore for gaining access to the Spooling$-$Buffer. Define these semaphore variables and indicate their initial values that would make your code correct. Further assume that there are built$-$in library

functions: signal$()$ and wait$(),$ for guarding the critical sections.
