    <p>The new C11 standard provides a support for Multi-Threading.<br> My Questions are a bit diversified but definitely answerable.<br> I have had a look at the C11 <strong><a href="http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf" rel="noreferrer">n1570</a></strong> draft.<br> It says: </p> <blockquote> <p>support for multiple threads of execution including an improved memory sequencing model, atomic objects, and thread-local storage (<code>&lt;stdatomic.h&gt;</code> and <code>&lt;threads.h&gt;</code>)</p> </blockquote> <p>What is the <strong>Improved memory sequencing model</strong>? How/What changes from the c99 Standard?</p> <p>Rather than just quotes from standard, I will appreciate if someone delves deeper in them and tries explaining the semantics involved.</p> <p>As I understand, C11 provides support for: </p> <ul> <li>Thread creation and Management </li> <li>Mutex</li> <li>Conditional Variables</li> <li>Thread Specific storage &amp;</li> <li>Atomic Objects</li> </ul> <p>I hope I didn't miss anything?<br> Since now the Standard library itself provides(will provide) all the functionalities needed for Multi-Threading, there would be no need for POSIX and such libraries(for Multi-Threading support) in future? </p> <p>Lastly, What compilers provide support for the above mentioned features? Are there any references as to timelines when these will be supported?<br> I remember for C++11 there was a link for compiler support and features, perhaps something like that?</p>

    3. COI'm close voting ('exact duplicate') because your first question (About the sequencing model) has already been answered. It's difficult to answer questions that contain multiple questions, because someone may only know about part of your question - their answer can therefore never be accepted, because it doesn't answer the whole question, and there may never be an accepted answer. Please split your question up, and remove the exact duplicate part (or indicate why it's different from the questions I linked).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
