这个服务器端的线程？

lq651659889 2011-01-06 06:10:07

程序代码如下，不用线程的话客户端是可以连接的，但一用线程客户端一连接就报错说：accept:Invalid argument
程序如下
#include<sys/types.h>
#include<sys/socket.h>
#include<stdio.h>
#include<stdlib.h>
#include<errno.h>
#include<unistd.h>
#include<netinet/in.h>
#include<string.h>

#define Run 1

#define PORT 4321
#define BUFFER_SIZE 1024
#define MAX_CONNECT 5

int client_fd;
char re[BUFFER_SIZE];

void* thread_server(void*);

int main(void)
{
struct sockaddr_in server_sockaddr,client_sockaddr;
int sin_size,recvbytes;
int sockfd;
char buf[BUFFER_SIZE];
int sendbytes;
pthread_t ptid;

if((sockfd = socket(AF_INET,SOCK_STREAM,0)) == -1)
{
perror("socket");
exit(1);
}

printf("Socket id=%d\n",sockfd);

server_sockaddr.sin_family = AF_INET;
server_sockaddr.sin_port = htons(PORT);
server_sockaddr.sin_addr.s_addr = INADDR_ANY;
bzero(&(server_sockaddr.sin_zero),8);

int i=1;
int len=sizeof(i);
setsockopt(sockfd,SOL_SOCKET,SO_REUSEADDR,&i,len);

if(bind(sockfd,(struct sockaddr*)&server_sockaddr,
sizeof(struct sockaddr)) == -1)
{
perror("bind");
exit(-1);
}
printf("bind success!\n");

if(listen(sockfd,MAX_CONNECT) == -1)
{
perror("listen");
exit(1);
}
printf("listening....\n");

if((client_fd = accept(sockfd,(struct sockaddr*)&client_sockaddr,
(socklen_t*)&sin_size)) == -1)
{
perror("accept");
exit(1);
}

#if Run
int re_thread;
if((re_thread = pthread_create(&ptid,NULL,(void*)thread_server,NULL
))== -1)
{
perror("pthread_create");
exit(1);
}
#endif

while(1)
{
/*#if !Run
memset(buf,0,sizeof(buf));
if((recvbytes = recv(client_fd,buf,BUFFER_SIZE,0)) != -1)
{
printf("received a message:%s",buf);
//perror("recv");
//exit(1);
}
#endif*/

printf("send a message:");
memset(buf,0,sizeof(buf));
fgets(buf,sizeof(buf),stdin);
if((sendbytes = send(client_fd,buf,BUFFER_SIZE,0)) == -1)
{
perror("send");
exit(1);
}
}

#if Run
pthread_join(ptid,NULL);
#endif
close(sockfd);

return 0;
}

void* thread_server(void*p)
{
int recvbytes;
while(1)
{
memset(re,0,sizeof(re));
if((recvbytes = recv(client_fd,re,BUFFER_SIZE,0))
== -1)
{
perror("recv in thread");
pthread_exit((void*)1);
}
else
printf("recved a message:%s",re);
}
}

望高手指点。。。。
