1. What's the effect of not calling curl_multi_perform immediately again, even though if it returns CURLM_CALL_MULTI_PERFORM ? What impact or exceptions it can cause.
You're slowing down the transfer. But we ditched the CURLM_CALL_MULTI_PERFORM return code a long time ago and only libcurls before 7.20.0 ever returns that.
2. What is the Significance of max_fd = 0 set by curl_multi_fdset. Any special considerations ?
max_fd = 0 is no special case really, it just means that a single file descriptor is in use: 0.
max_fd = -1 however, is a special case and it is quite clearly documented: http://curl.haxx.se/libcurl/c/curl_multi_fdset.html
Or do you have questions left after reading that? -- / daniel.haxx.se ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
