Hello
I am trying to simulate a tick timer under cygwin but it does not work :
with the following code :

 /* Initialise timer structure */
  interval.it_interval.tv_sec = 1;
  interval.it_interval.tv_usec = 0;
  interval.it_value.tv_sec = 1;
  interval.it_value.tv_usec = 0;
  
   /* Initialise virtual timer */
   if (!sigaction (SIGVTALRM, &sigact, 0)) 
      { 
      if ( (err=setitimer (ITIMER_PROF, &s_Rtk_interval, NULL)) <0)
     	 {printf ("StartTimer could not setitimer %d\n",err);
     	 printf ("errno errno = %d (%s).\n", errno, strerror(errno));

          exit (0); 
	 }
      }
   else 
      { 
      fprintf( stderr, "Erreur :%d\n", errno ); 
      }

I got the invalid argument (errno) error ??
did someone manage the use of virtual timer under cygwin?
thanks
gilles
