命名管道进程通信
效果：server读取client发送的字符串。
?
server：
// named-pipe-server.cpp
#include
#include
using namespace std;
char buf[100];
HANDLE hpipe;
DWORD rlen=0,wlen=0;
void f_create(){
hpipe=CreateNamedPipe("\\\\.\\pipe\\me",PIPE_ACCESS_DUPLEX ,
PIPE_TYPE_MESSAGE|PIPE_WAIT ,PIPE_UNLIMITED_INSTANCES,0,0,0,NULL);
if(ConnectNamedPipe(hpipe, 0)==FALSE){//等待客户端链接
cerr<<"链接成功\n"<?
client：
//named-pipe-client.cpp
#include
#include
#include
using namespace std;
char buf[100];
HANDLE hpipe;
DWORD rlen=0,wlen=0;
void f_connect(){
WaitNamedPipe("\\\\.\\pipe\\me",NMPWAIT_WAIT_FOREVER);//等待连接
hpipe=CreateFile("\\\\.\\pipe\\me",
GENERIC_READ | GENERIC_WRITE, 0,
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);//打开管道
if(hpipe==INVALID_HANDLE_VALUE) cerr<<"open named pipe error\n";
else cout<<"open named pipe ok\n";
}
void f_write(char *a){
if(WriteFile(hpipe,a,256,&wlen,0)==FALSE){
cerr<<"client write error\n";
}
else{
cout<<"client write ok. context is:"<?
control：
//通过编程实现先开启server。再打开 client。#include #include using namespace std; int main(int argc, char *argv[]) { system("start named-pipe-server.exe");//start 不能漏 Sleep(1000); system("start named-pipe-client.exe"); return 0; }
