#include <sys/stat.h>
#include <fcntl.h>
int main(int arfc,char *argv[])
{
int i;
char buf[10];
int zhangjian;
char buf1[10] = "zhangjian";
zhangjian=open("/dev/mydev",O_RDWR);
if(zhangjian==-1)
{
    printf("Can't open the file!\n");
        return 0;
}
write(zhangjian,buf1,10);
read(zhangjian,buf,10);
printf("%s\n",buf);
close(zhangjian);
return 0;
