Linux issues on setting a timer function
- by laura
I am creating a process with 2 children, 1 of the children is responsible to read questions (line by line from a file), output every question and reading the answer, and the other one is responsable to measure the time elapsed and notify the user at each past 1 minute about the remaining time. My problem is that i couldn't find any useful example of how i can make this set time function to work. Here is what i have tried so far. The problem is that it outputs the same elapsed time every time and never gets out from the loop.
#include<time.h>
#define T 600000
int main(){
clock_t start, end;
double elapsed;
start = clock();
end = start + T;
while(clock() < end){
elapsed = (double) (end - clock()) / CLOCKS_PER_SEC;
printf("you have %f seconds left\n", elapsed);
sleep(60);
}
return 0;
}
