Oops, I may have confused you writing about CURL_WRITEFUNC_PAUSE in my
first message. I am not downloading but uploading data. This data is
becoming available through an internal process over which I have no
control, and I am sending this data through libcurl API. Is it OK to
block in the read callback until some more data is available in this
case?

Thank you,
