That's only for file upload. I have managed to do it directly with another library (by providing the header "Range: bytes=x-y") but I have to buy that library.
Would like to see this in libcur but source code is new for me to add something like this.

Now is there any easy way to use libcur to do this.

It is also called to rewind a stream when doing a HTTP PUT or POST with a multi-pass authentication method. The function shall work like "fseek" or "lseek" and accepted SEEK_SET, SEEK_CUR and SEEK_END as argument for origin, although (in 7.18.0) libcurl only passes SEEK_SET. The callback must return 0 on success as returning non-zero will cause the upload operation to fail. If you forward the input arguments directly to "fseek" or "lseek", note that the data type for offset is not the same as defined for curl_off_t on many systems! (Option added in 7.18.0) CURLOPT_SEEKDATA Data pointer to pass to the file read function. If you use the CURLOPT_SEEKFUNCTION option, this is the pointer you'll get as input. If you don't specify a seek callback, NULL is passed. (Option added in 7.18.0) ---- Currently, there's no wrapper around those options in cURLpp. I'll try to add those for the next version. However it shouldn't be there until a month. > > > Any help (or other librarys that can) would be appreciated. > > > > Mark -- Jean-Philippe Barrette-LaPierre _______________________________________________ cURLpp mailing list [email protected] http://www.rrette.com/mailman/listinfo/curlpp _______________________________________________ cURLpp mailing list [email protected] http://www.rrette.com/mailman/listinfo/curlpp
