</p>
<p>While programming with multiple threads, sometimes one needs a construct which allows to suspend the execution of a set of running threads. This is normally required by an outside thread which wants to suspend the running threads for performing a specific action. The threads need to resume after the action in the same order in which they got suspended. </p>
<p>A thread gate (or gateway) allows you to do this. It acts like a gate through which only one thread can pass at a time. By default the gate is open, allowing all threads to "enter" the gate. When a thread calls "close", the gate is closed, blocking any threads which make a further call to "enter", till the gate is re-opened by the owner, whence the threads resume the order in which they got blocked.</p>
<p>The real-life parallel for this is a human operated level cross, which allows only one vehicle to pass at a time.</p>

<p>Print (1) packages used by a binary, and (2) the list of installed patches
related to these packages. If you have a binary that works with Solaris 10 update N, but doesn't with Solaris 10 update N-2, run this script on both platform and it will help you to find the patches you're looking for.</p>
<p>(1) is retrieved:</p>
<ul>
<li>By using pldd(pid) on the process you want to trace to get a list of loaded
shared library </li>
<li>By retrieving in the main /var/sadm/install/contents database
the list of package related to these shared libraries</li>
</ul>
<p>(2) is retrieved by parsing the output of the showrev -p command, given as
input of this script</p>
