代码说明:

  C++ 使用共享内存实现进程间通信。 文件映射是一种实现进程间单向或双向通信的机制。它允许两个或多个本地进程间相互通信。为了共享文件或内存,所有的进程必须使用相同的文件映射的名字或是句柄。   为了实现共享文件,第一个进程先调用CreateFile方法。接下来调用CreateFileMapping方法来创建一个文件映射对象。并为文件映射指明一个句柄和名称。由于事件,信号,互斥对象和文件映射等这些内核对象都共享同一个名字空间,所以如果这个名字和其他一个对象的名称重名的话那么将创建失败。(C++ use shared memory to achieve inter-process communication)

    OpenSS7 This the fourth public release of the OpenSS7 Master Package. See README in the release for a sub-package listing. Most of the sub-packages in the release are production grade for Linux Fast-STREAMS. All existing validation test suites run clean on supported distributions and architectures. It is unlikely that the OpenSS7 Master Package will be released as frequently as before. Sub-packages will be released more often. To rebuild the master package with a new sub-package release, simply replace the directory to which the sub-package belongs with the unpacked sub-package release and then rebuild the master package. This release provides support for recent distributions and tool chains. (OpenSS7 This the fourth public release o f the OpenSS7 Master Package. See README in the r elease for a sub-package listing.
