Stopping and continuing the execution of a process (using SIGCONT and SIGSTOP)

#include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include <sys/types.h> #include <sys/wait.h> int main(int argc, char* argv[]) { int pid = fork(); if (pid == -1) { return 1; } if (pid == 0) { while (1) { printf("Some output\n"); usleep(50000); } } else { kill(pid, SIGSTOP); int t; do { printf("Time in seconds for execution: "); scanf("%d", &t); if (t > 0) { kill(pid, SIGCONT); sleep(t); kill(pid, SIGSTOP); } } while (t > 0); kill(pid, SIGKILL); wait(NULL); } return 0; }
