在Asio中,async_connect函数用于发起异步连接操作。当连接成功建立或发生错误时,会调用用户指定的回调函数。然而,如果在调用async_connect后未调用回调函数,可能有以下几个原因: 异步连接尚未完成:异步操作需要一定的时间来完成,可能是由于网络延迟或其他原因导致连接尚未建立。在这种情况下,需要等待连接完成后才能调用...
独立asio是一个跨平台的C++网络编程库,提供了一套异步的网络编程接口。async_connect函数用于发起异步连接操作,它接受一个socket对象和一个远程端点作为参数,并在连接完成或发生错误时调用绑定的处理程序。 在使用async_connect函数时,需要先创建一个socket对象,并设置好相关的参数,如协议类型、IP地址和端口号等。...
I came across#92when I needed this behavior for a use case of mine and wanted to save future searchers the trouble with an explicit example in the docs. Let me know if there's anything I can change. My IDE didn't seem pleased with the formatting, even when adding the hiddenasync fn ...
