應(yīng)用場(chǎng)景：
做了一個(gè)client，去和Message Middleware通信，實(shí)時(shí)獲取消息中間件以topic方式(不是Queue，對(duì)Message Middleware來(lái)說(shuō)，Queue是發(fā)送一個(gè)destination，topic可以發(fā)多個(gè))。
從實(shí)時(shí)獲取的角度來(lái)說(shuō)，需要啟一個(gè)線程，接收Message Middleware消息，然后做場(chǎng)景需要的處理。創(chuàng)建線程的函數(shù)如下所示：
// for compilers which have it, we should use C RTL function for thread
// creation instead of Win32 API one because otherwise we will have memory
// leaks if the thread uses C RTL (and most threads do)
#if defined(__VISUALC__) || \
(defined(__BORLANDC__) && (__BORLANDC__ >= 0x500)) || \
(defined(__GNUG__) && defined(__MSVCRT__))
typedef unsigned (__stdcall *RtlThreadStart)(void *);
m_hThread = (HANDLE)_beginthreadex(NULL, 0,
(RtlThreadStart)
wxThreadInternal::WinThreadStart,
thread, CREATE_SUSPENDED,
(unsigned int *)&m_tid);
#else // compiler doesn't have _beginthreadex
m_hThread = ::CreateThread
(
NULL, // default security
0, // default stack size
(LPTHREAD_START_ROUTINE) // thread entry point
wxThreadInternal::WinThreadStart, // the function that runs under thread
(LPVOID)thread, // parameter
CREATE_SUSPENDED, // flags
&m_tid // [out] thread id
);
#endif // _beginthreadex/CreateThread
note: there should be a function definition before these lines.eg:
DWORD wxThreadInternal::WinThreadStart(wxThread *thread)
