一直搞不懂这个定时器怎么用的,正好程序里面有个例子,实验了一下
主要是这个drive(),这个定时器需要自己调用drive驱动
tf->driveTimer(); boost::this_thread::interruptible_wait(100);
interruptible_wait表示等待100ms,如果时间是100ms,就没有定时器到时间,1000ms则每次myTimer1总会执行,myTimer2,myTimer2则不一定,2000ms则myTimer1,myTimer2则每次执行,
myTimer3不一定,3000ms则三个定时器都会执行,看这个wait时间的多少。时间少了就没有定时器执行,多了则都会执行。具体程序中用,还需研究。
