ioctl里面的参数

linuxcici

ioctl(fdusb,HIDIOCINITREPORT,NULL);


中的HIDIOCINITREPORT请问代表的是什么东西呢?  如果对于以后再对于一些宏的东西不了解. 请问有什么方法可以在系统里面
可以查找出来呢?

看源码
/*
* Initialize all reports
*/
        /*
         * The Set_Idle request is supposed to affect only the
         * "Interrupt In" pipe. Unfortunately, buggy devices such as
         * the BTC keyboard (ID 046e:5303) the request also affects
         * Get_Report requests on the control pipe.  In the worst
         * case, if the device was put on idle for an indefinite
         * amount of time (as we do below) and there are no input
         * events to report, the Get_Report requests will just hang
         * until we get a USB timeout.  To avoid this, we temporarily
         * establish a minimal idle time of 1ms.  This shouldn't hurt
         * bugfree devices and will cause a worst-case extra delay of
         * 1ms for buggy ones.
