This is confusing. Prior to 7.20.0 there were only two return codes from curl_multi_perform: 1. CURLM_OK - Nothing currently to do. 2. CURLM_CALL_MULTI_PERFORM - curl_multi_perform needs to be called again. I originally used your examples of calling curl_multi_perform and did not find any issues with it. If CURLM_CALL_MULTI_PERFORM is no longer returned from curl_multi_perform, how do I know if curl_multi_perform needs to be called again? i.e. there is more pending data to transfer now? Sounds like moving past 20.0.0 will significantly change my logic.

CURLM_CALL_MULTI_PERFORM is deprecated and will never be returned, as documented. During the first decade or so of libcurl's multi interface, I never saw a single proper use of that feature. I did however see numerous mistakes and misunderstandings. That made me decide that the feature wasn't important or good enough, so since 7.20.0 CURLM_CALL_MULTI_PERFORM is no more. -- / daniel.haxx.se ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette:  http://curl.haxx.se/mail/etiquette.html
