linux 多线程学习

在C++中如果在类里面调用线程。以及在线程中使用类中的其他成员函数那么可以使用下面的方法

class CanProto{//头文件简写
。。。。。。
pubilc:
static void * Receive_Pthread(void *p);
}

函数调用
void * CanProto::Receive_Pthread(void *p)
{
    CanFrame frame;
    unsigned char *precvframe = (unsigned char *)&frame;
    const int can_frame_len = sizeof(CanFrame);
    int maxfd,ret;
    fd_set rfds;
    struct timeval timeout;
    timeout.tv_sec = 0;
    memset(&frame,0x00,sizeof(frame));




    while(1) {
        FD_ZERO(&rfds);
        FD_SET(m_fd,&rfds);
        timeout.tv_usec = 8000;
        memset(precvframe,0x00 ,can_frame_len);


        maxfd = m_fd +1;
        if((ret = select(maxfd,&rfds,NULL,NULL,&timeout)) < 0 ){
            PERROR("select");
        }
        if(ret > 0){
            int ret = read(m_fd,(char*)precvframe,can_frame_len);
            printf("ret = %d\n",ret);
            ((CanProto *)p)->printf_frame(frame.canID,frame.data,frame.len);


        }
    }
}
int CanProto::Start(void)主函数
{
    int rdlen;
    
    CanDev can;
    CmdProcess m_canProc;
    m_fd = can.Open();


    if(m_fd < 0)
	return 0;


    pthread_t pid;
    int pidbyte = pthread_create(&pid,NULL,send_ID,NULL);


    pthread_t pidt;
    int resepidt = pthread_create(&pidt,NULL,CanProto::Receive_Pthread,this);


    return 0;
}
