To Fabian

Thanks for your reply.
You mean return 0,it means the transfer is completed?
If I want to cancel the upload immediately, I should return CURL_READFUNC_ABORT.
Thanks for above.

And I have a trouble that xmlhttprequest upload by cUrl ,it doestn’t call read callback although I register callback to curl handle.
Do you have any idea?

Thanks again.

I think when read callback return 0,the transfer will be caceled.is<http://caceled.is> it right?

Please refer to http://curl.haxx.se/libcurl/c/curl_easy_setopt.html, which states that "The read callback may return CURL_READFUNC_ABORT to stop the current operation immediately, resulting in a CURLE_ABORTED_BY_CALLBACK error code from the transfer". You should not return 0 to abort a transfer.
