进程调度优先级算法基于时间片算法

实验代码：
#include<stdio.h>
#include<stdlib.h>
#include"procelink.h"
void main()
{
	process *PQ;
	int n;
	pcb pro1;
	Initlink(&PQ);
	printf("请输入进程个数:");
	scanf("%d",&n);
		printf("请输入各个进程的进程标识数ID,进程优先数，进程一占用时间片，进程还需占用时间片\n");
	for(int i=1;i<=n;i++)
	{
		printf("第%d进程：",i);
		scanf("%d%d%d%d",&pro1.ID,&pro1.PRIORITY,&pro1.CPUTIME,&pro1.ALLTIME);
		EnInitlink(PQ,pro1);
	}
	while(!IsEmpty(PQ))
	{
		dispatch(DeInitlink(PQ),PQ);
	}
	if(IsEmpty(PQ))
		printf("所有进程一运行完!\n");
	free(PQ);
}
