curl回调函数线程

Question

I have done some googling but haven't found the answer to this as of yet.

When you registrar a function with curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, function) is that function guaranteed to be completed before curl_easy_perform(curl) returns? Or is it possible that function is being ran in parallel and may still be running when the easy_perform returns?

Answer 1

尽管我没有经验性的源文件+行号来支持此功能，但多年来在各种项目中使用libcurl多次，但我可以自信地说：是的，curl_easy_perform将阻塞直到您提供的write函数完成被调用。
