+应用层可以使用select函数查询设备当前的状态，以便用户程序获知是否能对设备进行非阻塞的访问. + +使用select函数需要在设备驱动程序中添加file_operations->poll接口支持. + +一个典型的字符驱动程序的file_operations->poll函数的实现如下 + +```c +static unsigned int my_poll(struct file *file, struct poll_table_struct *wait) +{ + unsigned int mask = 0; + poll_wait(file, & outq, wait);//把当前进程添加到等待列表 + if (0 != bta->read_count)//如果有数据 + mask |= (POLLIN | POLLRDNORM); + return mask; +} +``` + + +驱动程序中的poll函数返回的标志如下： + +```c +#define POLLIN 1 //设备可以无阻塞地读取 +#define POLLPRI 2//可以无阻塞地读取高优先级数据(带外数据) +#define POLLOUT 4//设备可以无阻塞地写入 +#define POLLERR 8//设备发生错误 +#define POLLHUP 16//当读取设备的进程到达文件尾部 +#define POLLNVAL 32 //请求无效 +#define POLLRDNORM 64//常规数据已经就绪 +#define POLLWRNORM POLLOUT +#define POLLRDBAND 128//可以从设备读带外数据 +#define POLLWRBAND 256//可以向设备写带外数据 +#define POLLMSG 0x0400 +#define POLLREMOVE 0x1000 +#define POLLRDHUP 0x2000 +``` + +应用层多路I/O选择函数select的原型如下： + +```c +int select(int numfds, fd_set *readfds, fd_set +*writefds, fd_set *exceptfds, struct timeval *timeout); +``` + +其中readfds、writefds、exceptfds分别是被select函数监视的读、写和异常处理的文件描述符集合，numfds的值是需要检查的号码最高的文件描述符加1。timeout参数是一个指向struct timeval类型的指针，它可以使select函数在等待timeout时间后若没有文件描述符准备好则返回。文件描述符集常用函数接口如下： + +```c +FD_ZERO(fd_set *set)//清除一个文件描述符集； + +FD_SET(int fd,fd_set *set)//将文件描述符fd加入文件描述符集中； + +FD_CLR(int fd,fd_set *set)//将文件描述符fd从文件描述符集中清除； + +FD_ISSET(int fd,fd_set *set)//判断文件描述符fd是否被置位。 +``` +

data[256]; + fd_set rfds; //读描述符集合 + fd_set wfds; //写描述符集合 + int retval=0; + while(1) + { + FD_ZERO(&rfds); + FD_SET(fd, &rfds); + select(fd+1, &rfds, &wfds, NULL, NULL); //多路选择 + if(FD_ISSET(fd,
