Data Structures and Functions
- Design and implement the extended version of the manager, including:
- PCB, RCB, and RL data structures
- functions create(), destroy(), request(), release(), timeout(), scheduler(), init()
- Design and implement the shell (see command language and output specifications)
- Instantiate manager to include the following at start-up:
- A process descriptor array PCB[16]
- A resource descriptor array RCB[4] with multiunit resources
- RCB[0] and RCB[1] have 1 unit each; RCB[2] has 2 units; RCB[3] has 3 units
- A 3-level RL
- The init function should always perform the following tasks:
- Erase all previous contents of the data structures PCB, RCB, RL
- Create a single running process at PCB[0] with priority 0
- Enter the process into the RL at the lowest-priority level 0
