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;
}
