1、服务器程序

#include<stdio.h>
#include<sys/types.h>
#include<sys/socket.h>
#include<pthread.h>
#include<netinet/in.h>
#include<arpa/inet.h>
#include<stdlib.h>
#include<string.h>
#define PORT 2003

void *read_msg(void *arg)
{
int fd = *((int *)arg);
int nread = 0;
char buffer[1024];

while((nread = read(fd,buffer,sizeof(buffer))) > 0)
{
buffer[nread] = '\0';
printf("Message from client:%s\n",buffer);
memset(buffer,0,sizeof(buffer));
}
}

void *write_msg(void *arg)
{
char buf2[1024];
int fd = *((int *)arg);

while(1)
{
fgets(buf2,1024,stdin);
write(fd,buf2,100);
sleep(2);
}
}

int main()
{
int sockfd,new_fd;
struct sockaddr_in server_addr;
struct sockaddr_in client_addr;
int r_byte;
int size;
char buffer[1024];
pthread_t id;

if((sockfd = socket(AF_INET,SOCK_STREAM,0)) < 0)
{
printf("socket error!\n");
}

bzero(&server_addr,sizeof(struct sockaddr_in));
server_addr.sin_family = AF_INET;
server_addr.sin_port = htons(PORT);
server_addr.sin_addr.s_addr = htonl(INADDR_ANY);

if((bind(sockfd,(struct sockaddr*)&server_addr,sizeof(struct sockaddr))) < 0)
{
printf("bind error!\n");
}

if(listen(sockfd,5) < 0)
{
printf("listen error!\n");
}

while(1)
{
size = sizeof(struct sockaddr_in);
printf("accepting...\n");
if((new_fd = accept(sockfd,(struct sockaddr*)&client_addr,&size)) < 0)
{
printf("accept error!\n");
}
fprintf(stderr,"Server get connection from %s\n",inet_ntoa(client_addr.sin_addr));

pthread_create(&id,NULL,(void *)read_msg,(void *)&new_fd);
pthread_create(&id,NULL,(void *)write_msg,(void *)&new_fd);
}
close(sockfd);
exit(0);
}

2、客户端程序

#include<stdio.h>
#include<sys/types.h>
#include<sys/socket.h>
#include<stdlib.h>
#include<arpa/inet.h>
#include<string.h>
#include<pthread.h>
#define PORT 2003

void *read_msg(void *arg)
{
int fd = *((int *)arg);
int nread = 0;
char buffer[1024];

while((nread = read(fd,buffer,sizeof(buffer))) > 0)
{
buffer[nread] = '\0';
printf("Meaasage from server is:%s\n",buffer);
memset(buffer,0,sizeof(buffer));
}
}

void *write_msg(void *arg)
{
char buf2[1024];
int fd = *((int *)arg);
while(1)
{
fgets(buf2,1024,stdin);
write(fd,buf2,5);
sleep(2);
}

}
int main()
{
int sockfd;
struct sockaddr_in server_addr;
char buffer[1024];

if((sockfd = socket(AF_INET,SOCK_STREAM,0)) < 0)
{
printf("socket error!\n");
}
bzero(&server_addr,sizeof(struct sockaddr_in));
server_addr.sin_family = AF_INET;
server_addr.sin_port = htons(PORT);
server_addr.sin_addr.s_addr = inet_addr("192.168.1.145");

if(connect(sockfd,(struct sockaddr*)&server_addr,sizeof(server_addr)) < 0)
{
printf("connect error!\n");
}

pthread_t id;

pthread_create(&id,NULL,(void *)read_msg,(int *)&sockfd);

printf("please input char :");
while(1)
{
//printf("please input char :");
scanf("%s",buffer);
write(sockfd,buffer,strlen(buffer));
}
close(sockfd);
exit(0);
}
