You would need to access the underlying thread primitive and assign a name in a system dependent manner. Debugging and crash logs are inherently system dependent and boost::thread is more about non-system-dependency, i.e. about portability.

It seems ( <a href="http://www.boost.org/doc/libs/1_43_0/doc/html/thread.html" rel="nofollow noreferrer">http://www.boost.org/doc/libs/1_43_0/doc/html/thread.html</a> ) that there is no documented way to access underlying system resources for a boost thread. (But I have never used it myself so I may miss something.)

Edit: (As David writes in the comment) <a href="http://www.boost.org/doc/libs/1_43_0/doc/html/thread/thread_management.html#thread.thread_management.thread.nativehandle" rel="nofollow noreferrer">http://www.boost.org/doc/libs/1_43_0/doc/html/thread/thread_management.html#thread.thread_management.thread.nativehandle</a>

I'm using boost 1.50.0 on Win32 + VS2010 and <code>thread::native_handle</code> contains number which I didn't manage to pair to anything in system. On the other hand, the <code>thread::get_id()</code> method returns directly windows thread ID in form of a hexadecimal string. Notice that the value returned is platform specific, though. The following code does work under Boost 1.50.0 + Win32 + VS2010. Parts of code reused from <a href="http://blogs.msdn.com/b/stevejs/archive/2005/12/19/505815.aspx" rel="nofollow">msdn</a>

<pre><code>const DWORD MS_VC_EXCEPTION = 0x406D1388;
#pragma pack(push, 8)
typedef struct THREADNAME_INFO {
 DWORD dwType; // Must be 0x1000.
 LPCSTR szName; // Pointer to name (in user addr space).
 DWORD dwThreadID; // Thread ID (-1=caller thread).
 DWORD dwFlags; // Reserved for future use, must be zero.
} THREADNAME_INFO;
#pragma pack(pop)

void _SetThreadName(DWORD threadId, const char* threadName) {
 THREADNAME_INFO info;
 info.dwType = 0x1000;
 info.szName = threadName;
 info.dwThreadID = threadId;
 info.dwFlags = 0;
 __try {
 RaiseException( MS_VC_EXCEPTION, 0, sizeof(info)/sizeof(ULONG_PTR), (ULONG_PTR*)&amp;info );
 }
 __except(EXCEPTION_EXECUTE_HANDLER) {
 }
}
void SetThreadName(boost::thread::id threadId, std::string threadName) {
 // convert string to char*
 const char* cchar = threadName.c_str();
 // convert HEX string to DWORD
 unsigned int dwThreadId;
 std::stringstream ss;
 ss &lt;&lt; std::hex &lt;&lt; threadId;
 ss &gt;&gt; dwThreadId;
 // set thread name
 _SetThreadName((DWORD)dwThreadId, cchar);
}
</code></pre>

Call like this:

<pre><code>boost::thread* thr = new boost::thread(boost::bind(...));
SetThreadName(thr-&gt;get_id(), "MyName");
</code></pre>

Is it possible to give a name to a <code>boost::thread</code> so that the debuggers tables and the crash logs can be more readable? How?

Give a name to a boost thread?

调试器

Windows

是否可以为boost::thread命名，以便调试器表和崩溃日志更具可读性？多么?
