摘要： SigPipe:在linux下写socket的程序的时候，如果尝试send到一个disconnected socket上，就会让底层抛出一个SIGPIPE信号。这个信号的缺省处理方法是退出进程，大多数时候这都不是我们期望的。因此我们需要重载这个信号的处理方法。调用以下代码，即可安全的屏蔽SIGPIPE：static intdisableSIGPIPE(void){ struct sigaction... 阅读全文

摘要： On Mac OS X and Windows there are builtin CompareAndSwap functions you should be using anyway (InterlockedCompareExchange() and OSAtomicCompareAndSwapPtrBarrier() respectively). Thus will work rega... 阅读全文

摘要： SpinLock might be useful when a lock on a shared resource is not going to be held for very long. In such cases, on multi-core computers it can be efficient for the blocked thread to spin for a few cyc... 阅读全文

摘要： OpenOnload is not really an alternative to TCP, it is a user level implementation of the TCP/IP stack which is able to transfer directly from user space to the NIC. This avoids the multiple memory... 阅读全文

摘要： Try including "winsock2.h" before "windows.h" in your source code. There's an include guard in "winsock2.h" that prevents "winsock.h" from being pulled in. By default, "windows.h" trys to pull in "wi... 阅读全文
