c++ - 如何在c中给定毫秒后停止计时器

Question

 #include <stdio.h>
#include <time.h>   
int main (void)
{
double diff = 0.0;
time_t start;
time_t stop;
time(&start);
print("Enter millisecond to stop"); 

那么应该添加什么代码来在给定的计时器间隔后停止计时器

int seconds;
scanf ("%d",&seconds);
stop = 0;
while (stop < start + seconds)
    time(&stop);
