For +the FTP wildcard download, the target is curl_fileinfo structure (see +\fIcurl/curl.h\fP). The parameter \fIptr\fP is a pointer given by +\fICURLOPT_CHUNK_DATA(3)\fP. The parameter remains contains number of chunks +remaining per the transfer. If the feature is not available, the parameter has +zero value. + +Return \fICURL_CHUNK_BGN_FUNC_OK\fP if everything is fine, +\fICURL_CHUNK_BGN_FUNC_SKIP\fP if you want to skip the concrete chunk or +\fICURL_CHUNK_BGN_FUNC_FAIL\fP to tell libcurl to stop if some error occurred. +.SH DEFAULT +NULL +.SH PROTOCOLS +FTP +.SH EXAMPLE +TODO +.SH AVAILABILITY +This was added in 7.21.0 +.SH RETURN VALUE +Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. +.SH "SEE ALSO" +.BR CURLOPT_CHUNK_END_FUNCTION "(3), " CURLOPT_WILDCARDMATCH "(3), " -- cgit v1.2.3
