How do I implement the alloc_saved_regs function?

#include #include #include"homework4.h"

int main() { int i = 0; for(i = 0;i < 12; i++) { struct pcb_type *processControlBlock = create_new_pcb(); add_new_process(processControlBlock); } while(start != NULL) { print_Process(start->pcb_pt); start = start->who_follows; } system("Pause"); return 0; } struct saved_regs * alloc_saved_regs() {

} //creating a new PCB struct pcb_type* create_new_pcb() { struct pcb_type *process = malloc(sizeof(struct pcb_type)); process->proc_class = allocated_class++; process->proc_id = allocated_id++; process->proc_priority = allocated_prio; process->proc_state = 3; return process; } // Adding the pcb to a process_list void add_new_process(struct pcb_type *process) { //Adding to the type process struct process_list *processList = malloc(sizeof(struct process_list)); processList->pcb_pt = process; if(start == NULL) { start = processList; processList->who_follows = NULL; } else { processList->who_follows = start; start = processList; } } //To print the pcbs void print_Process(struct pcb_type *processControlBlock) { printf("index of process: %d ", *processControlBlock); printf("address_pcb = %ud ", &processControlBlock); printf("proc_id = %d ", processControlBlock->proc_id); printf("proc_class = %d ", processControlBlock->proc_class); printf("proc_priority = %d ", processControlBlock->proc_priority); printf("proc_state = %d ", processControlBlock->proc_state); }

#include #include

struct saved_regs { double reg1, reg2, reg32, reg_pc; }; struct pcb_type { int proc_id; int proc_priority; int proc_state; int proc_class; struct saved_regs *reg_pt; }; struct process_list { struct pcb_type *pcb_pt; struct process_list *who_follows; }; struct process_list *start = NULL; int allocated_id = 1; int allocated_prio = 1; int allocated_class = 1; struct saved_regs *alloc_saved_regs(); struct pcb_type *create_new_pcb(); void add_new_process(struct pcb_type *); void print_Process();

save regs is supposed to save the pcb information for each process. id, prioirity, state, class
