父进程未运行

Question

我试图在c中编写一个简单的SMS服务器，并且有一个生成2个进程的函数（一个用于监听，另一个用于写入），但父进程似乎没有正在运行（调试消息未被打印）尽管fork调用没有生成错误...

void connection (int sock, char username[], int *rear, int *front, msg queue_array[])
{
    int n, pid;
    char buffer[256], dest[64]; 
    pid = fork();
    if(pid < 0) error("ERROR on fork call");
    while(1)
    {
        if(pid > 0)
        {
            bzero(buffer,256);
            n = read(sock,buffer,255);

            if (n < 0) error("ERROR reading from socket");

            printf("Here is the full message: %s\n",buffer);

            //n = write(sock,"I got your message!\n",18);
            //if (n < 0) error("ERROR writing to socket");
            //interpret(buffer, username);

            //TEMPORARY!!!!!    

            msg *temp;
            temp = (msg *)(malloc(sizeof(msg)));
            strcpy(temp->dest, "destiny");
            strcpy(temp->text, "blahblah");
            insert(temp, rear, front, queue_array); //Por a mensagem na queue

        }
        else
        {
            sleep(1); 
            /*Verificar se a file está vazia*/
            printf("hi?");
            printf("yooooo: %d", *front);
            if(*front != -1) 
            {
                /*verificar se a primeira mensagem da queue é destinada a esta pessoa*/
                strcpy(dest, queue_array[*front].dest); 
                printf("%s != destiny", dest);
                if(strcmp(dest, "destiny") == 0)
                {
                    printf("passou o teste\n");
                    strcpy(buffer, queue_array[*front].text);
                    delete(rear, front);
                    n = write(sock,buffer,strlen(buffer));
                    if (n < 0) error("ERROR writing to socket");
                }
            }
        }   
    }
}

非常感谢任何帮助。
