c++ - A Unique and Constant Identifier for a pthreads thread? -

-

I have estimated that a pthread_t remains constant for a given thread - its entirety For life, but my experiment is false to prove this assumption if the ID is not completely stable in a given yarn, how can I store a pthread_t so that the thread Can you use pthread_join to block until it ends?

For other reasons, it would be helpful to know how to get a unique identifier for a thread that I can change back and backward in pthread_t . Is there a way to do this?

There are a lot of big information, but I had a difficult time finding useful questions for answering these questions. I appreciate any help / consultation that I can get!

Edit: Also, I'm not sure why, but sleeping (1) and sleeping for 1 second on the front of each new thread (within the thread's function) . This is probably moving in the form of straw, but can the pthread_t value be fleeting during the beginning of a new thread or something ??

You can not trust a pthread_t , but you are unique To determine whether the two thread IDs are identical, use the pthread_equal () to use it. 

  name pthread_equal - Compare thread id # include & lt; Pthread.h & gt; Int pthread_equal (pthread_t t1, pthread_t t2); The description pthread_equal () function compares thread IDs t1 and t2. Return value The pthread_equal () function returns non-zero if thread ID T1 and T2 match the same thread. Otherwise, this will return zero to

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it.

There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for.

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
