• Process Management SysCalls

  • No argument forms:
    • int SimpleCreateProcess(char *programName);
  • Creates a process and returns a system-unique process ID (PID) (another UNIX-ism)
    • void SimpleExit(void);
  • SimpleExit() effectively ends the process’s execution and releases resources
    • void SimpleWait(int pid);
  • SimpleWait() will wait for the process with the specified PID to perform a SimpleExit()

• Notice implicit “parallel” execution
