这种匿名管道，和读写文件类似。最好是一个进程读，一个进程写，适合单向通信，不适于双向通信，双向通信容易导致的问题是有可能，读到自己进程刚才写的内容。

纯手工代码，没有一丝拷贝

父进程代码：

// PipeServer.cpp : 定义控制台应用程序的入口点。//#include "stdafx.h"#include 
     
      #include 
      
       using namespace std;#define BUFF_SIZE 1024void Test(){    SECURITY_ATTRIBUTES sec_handle = {
   0};    sec_handle.bInheritHandle = TRUE;    sec_handle.lpSecurityDescriptor = NULL;    sec_handle.nLength = sizeof(sec_handle);    HANDLE hReadPipe = INVALID_HANDLE_VALUE;    HANDLE hWritePipe = INVALID_HANDLE_VALUE;    BOOL bCrtPipeOk = CreatePipe(&hReadPipe,&hWritePipe,&sec_handle,BUFF_SIZE);    if(!bCrtPipeOk) return ;    STARTUPINFO siStartInfo;    ZeroMemory( &siStartInfo, sizeof(STARTUPINFO) );    siStartInfo.cb = sizeof(STARTUPINFO);      PROCESS_INFORMATION piProcInfo;      ZeroMemory( &piProcInfo, sizeof(PROCESS_INFORMATION) );     TCHAR szCommandLine[256] = {
   0};     _stprintf_s(szCommandLine,_T("-hReadPipe %d -hWritePipe %d"),hReadPipe,hWritePipe);      if(!::CreateProcess(        _T("PipeClient.exe"),        szCommandLine,        NULL,        NULL,        TRUE,        0 | CREATE_NEW_CONSOLE,        NULL,        NULL,        &siStartInfo,        &piProcInfo))      {          int nError = ::GetLastError();          cout<<"创建进程失败:"<
