客户端需要根据域名获取对应的IP地址时,如果不久前已经查询过该域名对应的IP地址,那么直接从本地DNS解析器缓存中获取(dns_lookup函数)。否则,客户端就以DNS客户的身份,向DNS服务器发出查询请求报文(dns_enqueue函数,此时返回状态ERR_INPROGRESS正在处理,后续dns_tmr函数会周期处理请求队列的内容)。 该函数需要周期处理...

"netconn_write" worked (it also returned ERR_INPROGRESS). Could anyone of the developers please give me some advice in how to use the non-blocking connect feature, or how it is supposed to work? I don't even know, if the mechanism I use is intended to be solution for the ...
