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
