Okay perhaps this is even less ambiguous: When CURLOPT_NOPROGRESS is set to 0, enabling progress calculations, this function will be called instead of its internal equivalent. This function is called multiple times per second when data is being transfered, and roughly every second when not. OR This function is called at least once a second, and generally many times per second when data is being transfered quickly. ________________________________ From: NSRT Mail account. <joecool22us@yahoo.com> To: Daniel Stenberg <daniel@haxx.se>; libcurl development <curl-library@cool.haxx.se> Sent: Friday, June 14, 2013 12:59 AM Subject: Re: PROGRESSFUNCTION does not work as described How about: When CURLOPT_NOPROGRESS is set to 0, this function will be called instead of its internal equivalent.

Meaning the expectation is that if an operation takes 100 seconds, the callback will be called 100 times, or 100 times plus a small percentage. I don't think the calling frequency is a problem. I think the documentation can be improved, indeed. The phrasing originates from the old days and it haven't kept up with the code changes.
