当我执行客户端文件和我连接到服务器时。发生总线错误10。 并且服务器不显示板。我没错。 看起来一切都还好。
我已经找到了这个简单编程的两天时间。
帮帮我。
非常感谢!!真!!
答案 0 :(得分：0)
这里有一个适合多个用户的代码：
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <errno.h>
#include <string.h>
#include <sys/time.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <sys/wait.h>
int initializeServer(int port)
{
int srv_sock;
struct sockaddr_in srv_addr;
int yes = 1;
if ((srv_sock = socket(AF_INET, SOCK_STREAM, 0)) == -1)
{
perror("socket");
exit(1);
}
if (setsockopt(srv_sock, SOL_SOCKET, SO_REUSEADDR, &yes, sizeof(int)) == -1)
{
perror("setsockopt");
exit(1);
}
srv_addr.sin_family = AF_INET;
srv_addr.sin_addr.s_addr = htonl(INADDR_ANY);
srv_addr.sin_port = htons(puerto);
memset(&(srv_addr.sin_zero), '\0', 8);
if (bind(srv_sock, (struct sockaddr *) &srv_addr, sizeof(struct sockaddr_in)) == -1)
{
perror("bind");
exit(1);
}
if (listen (srv_sock, BACKLOG) == -1)
{
perror("listen");
exit(1);
}
return srv_sock;
}
这是您需要接受客户端的另一个功能。您必须在同一.c文件中找到这两个函数：
int acceptCliente(int srv_sock) //srv_sock is the socket which the multiplexor gives you
{
int cli_sock;
struct sockaddr_in cli_addr;
int sin_zero = sizeof(struct sockaddr_in);
if ((cli_sock = accept(srv_sock, (struct sockaddr *) &cli_addr, &sin_zero)) == -1)
{
perror("accept");
exit(1);
}
return cli_sock;
}
因此，要使用此代码，您应该链接到.h文件，并以这种方式在主函数中调用它：
#include "server.h" //you can name it whatever you want
#define port 10000 //use any port you want, but it recommended to use over 1024
typedef struct {
uint32_t size;
char data[256];
} __attribute__((packed)) t_data;
int main(int argc, char *argv[])
{
int srv_sock = initializeServer(port);
while(1)
{
t_data package; //struct to store the info
bzero(package.data, 256);
int nbytes = recv(cli_sock, &package, sizeof(t_data), MSG_WAITALL);
if (nbytes < 0)
{
log_error(logger, "Error while receiving the message.");
exit(1);
}
if (nbytes == 0)
{
close(cli_sock);
//cliente disconnected
}
if (nbytes > 0)
{
//do something with the data =)
}
}
return EXIT_SUCCESS;
}
这取自我与大学中的一些合作伙伴所做的操作系统工作。我希望它有所帮助！
