  *    DESCRIPTION:	定义windows 和unix/linux(POSIX)系统下互斥锁、多线程和socket的差别
  *					允许此net4cpp库在windows和unix/linux下运行

  *		unix/linux下编译此库说明 :
  *		Sun os下编译时要指定-D__STL_PTHREADS宏，连接时指定-lnsl -lsocket -lpthread 库
  *     linux下编译时可以不指定-D__STL_PTHREADS宏，连接时要指定-lnsl -lpthread 库
  **********************************************************************************************************
  *		windows，vc中编译说明
  *		1、此库用到了winsocket ，因此在用此库前要调用WSAStartup()初始化winSocket库函数
  *		2、结束时要调用WSAClearup() winSocket库资源
  *		3、连接时指定libcmtd.lib或libcmt.lib库
  *		4、This program requires the multithreaded library. For example,
  * 			compile with the following command line:
  *     	CL /MT /D "_X86_" BEGTHRD.C
  *
  * 		If you are using the Visual C++ development environment, select the 
  * 		Multi-Threaded runtime library in the compiler Project Settings 
  * 		dialog box.
  *		
  *		The Multithread Libraries Compile Option
  *		To build a multithread application that uses the C run-time libraries, 
  *		you must tell the compiler to use a special version of the libraries (LIBCMT.LIB).
  *		To select these libraries, first open the Project Settings dialog box (Build menu) 
  *		and click the C/C++ tab. Select Code Generation from the Category drop-down list box. 
  *		From the Use Run-Time Library drop-down box, select Multithreaded. Click OK to return to editing.
  *
  *		From the command line, the Multithread Library compiler option (/MT) 
  *		is the best way to build a multithread program with LIBCMT.LIB. 
  *		This option, which is automatically set when you specify a multithreaded application 
  *		when creating a new project, embeds the LIBCMT library name in the object file.
