Next, you can pass the milliseconds parameter, which will be the amount of time JavaScript will wait before executing the code. One second is equal to one thousand milliseconds, so if you want to wait for 3 seconds, you need to pass 3000 as the second argument: function greeting still needs to be set to minutes (whattime * 60) but that can wait until I get it to work first. Code: void timer_handler (int signum) { cycle_images (); printf ("timer fired "); this was in the loadimage.c file where if it was called then the name would not need to be passed in a return. Code: diffs. +/* real_timer.c + + A demonstration of the use of (real-time) timers created using setitimer (). + + Usage: real_timer [secs [usecs [int-secs [int-usecs]]]] + Defaults: 2 0 0 0 + + The command-line arguments are the second and microsecond settings for + the timer's initial value and interval. + + The version of this code shown in the The function 'setitimer ()' is defined in the header file <sys/time.h> as given below; int setitimer ( int which, const struct itimerval *new_value, struct itimerval *old_value ); The first argument asks for the type of the timer that needs to be enabled. The OS provides each process to enable timers in three different modes. def test_setitimer_tiny(self): # bpo-30807: C setitimer () takes a microsecond-resolution interval. # Check that float -> timeval conversion doesn't round # the interval down to zero, which would disable the timer. self.itimer = signal.ITIMER_REAL signal.setitimer(self.itimer, 1e-6) time.sleep(1) self.assertEqual(self.hndl_called, True) Example #5 One periodic timer will expire in every 10 milli seconds and the other in every 5 milli seconds. First we called the initialize () function to initialize the module. In next three lines we started three timer by calling start_timer () function. We passed the interval, handler function, type of timer as input. Example of using timers and signal masks Raw timersDemo.c # include <stdlib.h> # include <unistd.h> # include <stdio.h> # include <signal.h> # include <time.h> /* This could be CLOCK_MONOTONIC or CLOCK_REALTIME depending on what you want */ # define CLOCKID CLOCK_REALTIME static void print_siginfo ( siginfo_t *si) { timer_t *tidp; int or; signal. SIG_IGN ¶ This is another standard signal handler, which will simply ignore the given signal. signal. SIGABRT ¶ Abort signal from abort (3). signal. SIGALRM ¶ Timer signal from alarm (2).
