Member Function Documentation

bool BeaconTimer::exec

(

)

[virtual]

Performs action after timeout. If it returns true the timer is not single shot, i.e. deleted right after exec().

Implements GpCoreTools::Timer.

{
  if(_fd<0) {
    return false;
  }
  static const char * msg="WAUB";
  if(sendto(_fd, msg, 4, 0,(struct sockaddr *) &_addr, sizeof(_addr))<0) {
    Log::write(0, "beacon sendto error: %s\n", strerror(errno));
  }
  return true;
}
