The module is there, kldload can't see it? I constructed a module and declared sysctl varible. If I use SYSCTL_DECL instead of SYSCTL_NODE, kldload will print that message.

相对于decorator, iterator, generator, metaclass 这些概念,descriptor是python所有概念中最难理解的一个了。尽管python documentation对其描述不多(基本上是一笔带过),以至于很多人忽略了这个概念。事实上,自己以前也忽略了它,只不过最近重温python时无意间发现了他,觉得非常有必要深入研究它。 自己的理解是建立在前人的基础之上的。不过,网上关于descriptor的资料实在是有限,下面是自己认为有参考价值的几个链接: 1.h...

公网静态ip:x.x.x.x 内网ip:xx.xx.xx.xx,使用Ipfire+Natd想做port Map,将xx.xx.xx.xx:110到公网:xxx.xxx.xxx.xxx:110上,能实现吗? 另使用ADSL是静态IP,还需要配置ppp吗?
if(write(fd,&data,2)<0) { printf("fd is %dn",fd); printf("i2c: watchdog write error.n"); printf("Error :%sn",strerror(errno)); close(fd); exit(-1); } 咝绣e誤打印信息為 fd is 3 i2c: watchdog write error Error: Bad File descriptor 在這段程序之前有ioctl設置,read等 都沒有出錯 到了write錯了,怎麽解決啊?
