c++ 创建 socket server
下面一段代码是创建socket server的代码片段:
需要引用的库包括:
#include <sys/types.h> #include <sys/socket.h> #include <arpa/inet.h>
int ss = -1; ss = socket(AF_INET,SOCK_STREAM,0); //获得句柄 if(ss < 0){ fprintf(stderr,"socket create error\n"); return false; } server_fd = ss; sockaddr_in server_addr; server_addr.sin_family = AF_INET; //协议类型 server_addr.sin_addr.s_addr = htonl(INADDR_ANY);//ip地址 server_addr.sin_port = htons(server_port);//端口号 int ret = bind(ss,(sockaddr*)&server_addr,sizeof(server_addr)); //绑定地址与端口 if(ret < 0){ fprintf(stderr,"error in bind\n"); return false; } ret = listen(ss,max_wait_num);//开始监听 if(ret < 0){ fprintf(stderr,"error in listen\n" ); return false; }
int sc = accept(ss,(sockaddr*)&from,&len); fprintf(stderr, "get one connection:[%d]\n", sc);
