Create a file to implement the following functions 

int enqueue(PROC **queue, PROC *p) // NOTE **queue { // enter p into queue by priority; FIFO if same priority } // remove and return first PROC from queue PROC *dequeue(PROC **queue) // NOTE **queue { // remove and return FIRST element in queue } int printFreeList(PROC *p) // print list p { // print the list as freeList=[pid pri]->[pid pri] ->..-> NULL } int printReadyQueue(PROC *p) // print list p { // print the list as readyQueue=[pid pri]->[pid pri] ->..-> NULL } int printSleepList(PROC *p) // print list p { // print the list as sleepList=[pid event]->[pid event] ->..-> NULL } int printChildList(PROC *p) // print list p { // print the list as childList=[pid status]->[pid status] ->..-> NULL } NOTE: you may write a SINGLE int printList(char *name, int what) for ALL the above print functions, name = "listname" what = 0: print [p->pid p->priority], what = 1: print [p->pid p->event], what = 2: print [p->pid p->status as STRING]
