curl_ws_recv() now receives data to fill up the provided buffer, but can return a partial fragment. The function now also get a pointer to a curl_ws_frame struct with metadata that also mentions the offset and total size of the fragment (of which you might be receiving a smaller piece). This way, large incoming fragments will be "streamed" to the application. When the curl_ws_frame struct field 'bytesleft' is 0, the final fragment piece has been delivered. curl_ws_recv() was also adjusted to work with a buffer size smaller than the fragment size. (Possibly needless to say as the fragment size can now be 63 bit large). curl_ws_send() now supports sending a piece of a fragment, in a streaming manner, in addition to sending the entire fragment in a single call if it is small enough. To send a huge fragment, curl_ws_send() can be used to send it in many small calls by first telling libcurl about the total expected fragment size, and then send the payload in N number of separate invokes and libcurl will stream those over the wire. The struct curl_ws_meta() returns is now called 'curl_ws_frame' and it has been extended with two new fields: *offset* and *bytesleft*. To help describe the passed on data chunk when a fragment is delivered in many smaller pieces. The documentation has been updated accordingly. Closes #9636
