计时器程序以调用c中的函数 [英] timer program to call function in c

问题描述

我想实现一个计时器，程序每5秒就会在其中调用一个函数.

我尝试在此代码中实现，但是它在for循环的内部很容易实现

Hi ,

I want to implement a timer in which program calls a function after every 5 seconds .

I tried to implement in this code but it is strucking in the inner for loop

#include<stdio.h>
#include<time.h>

int main()
{
 int a =10;
 int i=0;

 time_t seconds;
 seconds = time (NULL);
 for(;;)
 {
   for(;;)
   {
     if(time(NULL) - seconds <3)
     {
       printf("in if \n");
       foo();
       a++;
     }
     else
     {
       break;
     }
   }
   printf("%d",a);
  }
 return 0;
}
