    <p>As <a href="https://stackoverflow.com/a/14402485/12711">Useless mentioned in his answer</a>, strictly speaking the thread function called by the <code>pthread</code> library needs to be <code>extern "C"</code>. While a static member function works in nearly all cases, from a language lawyer point of view and at least one real life situation, it's not correct. See <a href="https://stackoverflow.com/a/2068048/12711">https://stackoverflow.com/a/2068048/12711</a> for details.</p> <p>However, you can have an <code>extern "C"</code> function provide the interface between the <code>pthread</code> library and your class template, but it does seem to require a tiny bit of overhead:</p> <pre><code>#include &lt;pthread.h&gt; struct trampoline_ctx { void* (*trampoline)(void*); void* obj; }; extern "C" void* trampoline_c(void* ctx) { struct trampoline_ctx* t = static_cast&lt;struct trampoline_ctx*&gt;(ctx); return (t-&gt;trampoline)(t-&gt;obj); } template &lt;class T, void * (T::*thread)()&gt; class Thread { public: int create(T *that) { ctx.trampoline = _trampoline; ctx.obj = that; return pthread_create(&amp;_handle, nullptr, trampoline_c, &amp;ctx); }; pthread_t getHandle() const { return _handle; }; private: static void * _trampoline(void *that) { return (static_cast&lt;T *&gt;(that)-&gt;*thread)(); }; pthread_t _handle; struct trampoline_ctx ctx; }; </code></pre> <p>I agree that composition rather than inheritance is probably a better model for threading most of the time.</p> <p>Of course, remember that C++11 provides <code>std::thread</code> which is a templated, non-inheritance design. And see <code>boost::thread</code> if C++11 isn't an option.</p>

    1. COThe std::thread solution won't work for me - first of all the RTOS I'm using makes it impossible to use stdlibc++ from the toolchain (yes, I also agree it's stupid), second of all the C++11 design is probably a big overkill for my 24kB or RAM and 24MHz chip, third of all - this implementation is OS dependant and there's no real OS here (; As for your solution - using dynamic alocation this overhead could be temporary (all 3 pointers are not needed when the thread is started), but that would bring heap to the picture (; there's always a tradeof (;

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.
