<div dir="ltr"><div>For time being I am calculating it this way:<br><br>#define typeaddr(addr, type, member) \<br> (type *)((char *)(addr) - offsetof(type, member))<br><br>CORE_mutex_Control *the_mutex= typeaddr(holder->Wait.queue, CORE_mutex_Control, Wait_queue);<br><br></div>Is there any other easy way? Like I guess we maintain objects so is there a way to get Object from its id. But its again convoluted problem - how to get id?<br></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr">Thanks,<div><br></div><div>Saurabh Gadia</div></div></div></div>
