当打开之后,执行onopen 当来到消息之后,执行onmessage 当断开之后,执行onclose,没有交给重新连接的方式,当我们进入项目的时候,会学习这个. audio可以开启麦克风,video可以开启摄像头. create_stream是创建成功后的回调函数,function(err)指的是创建失败之后的回调函数. create_stream需要一个东西接收这个函数.执行回调函...
join([timeout]):是用来阻塞当前上下文,直至该线程运行结束,一个线程可以被join()多次,timeout单位是秒。 name:一个字符串,只用于标识的目的。它没有语义。多个线程可以被赋予相同的名字。初始的名字通过构造函数设置。 getName()/setName():作用于name的两个函数,从字面就知道是干嘛的,一个是获取线程名,一个...
下面给出select接口的原型: FD_ZERO(int fd, fd_set* fds) FD_SET(int fd, fd_set* fds) FD_ISSET(int fd, fd_set* fds) FD_CLR(int fd, fd_set* fds) int select(int nfds, fd_set *readfds, fd_set *writefds, fd_set *exceptfds, struct timeval *timeout) 这里,fd_set 类型可以简单...

func_set_timeout This is a decorator you can use on functions to apply func_timeout. Takes two arguments, "timeout" and "allowOverride" If "allowOverride" is present, an optional keyword argument is added to the wrapped function, 'forceTimeout'. When provided, this will override the time...
