ActServerReceiverで受信したメッセージをActClientSenderで送信するとき、およびActSeverSenderでメッセージを送信するときにActClientSenderで直面している問題は、自分でメッセージを受信します。
struct Sending s =(struct Sending)index; ここでは、ActServerReceiverからportnoとsock_desを取得しています
これが私のコードです:
void *ActServerSender(void *index)
{
char msg[200];
struct sockaddr_in serv_addr;
int sock_des = socket(PF_INET,SOCK_DGRAM,0);
struct Sending *s=(struct Sending*)index;
serv_addr=s->serv_addr;
sock_des=s->sock_des;
printf("%d sock des",sock_des);
int sockaddr_len = sizeof(serv_addr);
printf("%d sock des",sock_des);
while(1)
{
int count=0;
printf("Enter Your Message\n");
while (scanf("%c", &msg[count]) )
{
if(msg[count]=='\n')
break;
count++;
}
msg[count]='\0';
printf("This message is send:%s\n",msg);
sendto (sock_des, msg, 200, 0, (struct sockaddr*)&serv_addr, sizeof(serv_addr));
}
}
void *ActsenderSender(void *index)
{
char msg[200];
struct sockaddr_in serv_addr;
int sock_des = socket(PF_INET,SOCK_DGRAM,0);
struct Sending *s=(struct Sending*)index;
serv_addr=s->serv_addr;
sock_des=s->sock_des;
int sockaddr_len = sizeof(serv_addr);
while(1)
{
printf("yahoooooooooooo!\n");
recvfrom(sock_des, msg, 200, 0, (struct sockaddr *)&serv_addr, &sockaddr_len);
printf("Message Received %s\n",msg);
fflush(stdout);
}
}
void *ActSenderReceiver(void *port)
{
pthread_t ActsenderSend;
int portno=(int)port;
printf("Your Port%d\n",portno);
char msg[200];
struct Sending s;
struct sockaddr_in serv_addr;
int sock_des = socket (AF_INET,SOCK_DGRAM,0);
serv_addr.sin_family = AF_INET;
serv_addr.sin_port = htons (portno);
serv_addr.sin_addr.s_addr = inet_addr ("127.0.0.1");
s.serv_addr=serv_addr;
s.sock_des=sock_des;
s.port=portno;
int j=0;
while(1)
{
if(j==2)
{
pthread_create( &ActsenderSend , NULL , ActsenderSender , (void*) &s);
}
int count=0;
printf("Enter Your Message or say Bye to leave the chat\n");
while (scanf("%c", &msg[count]) )
{
if(msg[count]=='\n')
break;
count++;
}
msg[count]='\0';
printf("This message is send:%s\n",msg);
if(strcmp(msg,"Bye")==0)
{
clientSender=1;
}
sendto (sock_des, msg, 200, 0, (struct sockaddr*)&serv_addr, sizeof(serv_addr));
j++;
}
}
void *ActAsAServerReceive(void *index)
{
char msg[200];
int portno=(int)index;
//UDP Connection
pthread_t ActServerSend;
struct Sending s;
printf("Your Port%d\n",portno);
struct sockaddr_in serv_addr;
int sock_des = socket(PF_INET,SOCK_DGRAM,0);
serv_addr.sin_family = AF_INET;
serv_addr.sin_port = htons(portno);
serv_addr.sin_addr.s_addr = inet_addr("127.0.0.1");
bind(sock_des,(struct sockaddr*)&serv_addr,sizeof(serv_addr));
int sockaddr_len = sizeof(serv_addr);
s.serv_addr=serv_addr;
s.sock_des=sock_des;
s.port=portno;
int count=0;
while(1)
{
if(count==2)
{
pthread_create( &ActServerSend , NULL , ActServerSender , (void*) &s);
//pthread_join(ActServerSend, NULL);
}
recvfrom(sock_des, msg, 200, 0, (struct sockaddr *)&serv_addr, &sockaddr_len);
printf("Message Received%s\n",msg);
fflush(stdout);
count++;
}
}
