Hi,

I think I did not explain myself clearly. What I've done is that for download I initiate a separate thread. The easyhandle is global. The dialog on which pause button is present is on the main thread. When user clicks pause I call curl_easy_pause() to pause the download. When user clicks Resume then I unpause using curl_easy_pause(). However the documentation of curl_easy_pause() clearly says that it must be called from the same thread where download is happening. 

1) Though pause\resume works in my case from different threads but I need to know if I'm doing something wrong here and should take a different approach because documentation suggests that I'm using curl_easy_pause() in a wrong way.

2) Now other option for me is CURL_WRITEFUNC_PAUSE but if I use it then how do I unpause?

Thanks,
-kashif

Hi,

Take a look at curl_easy_pause: http://curl.haxx.se/libcurl/c/curl_easy_pause.html

Best regards,
