It contains the offset in number of bytes that you +want the transfer to start from. Set this option to 0 to make the transfer +start from the beginning (effectively disabling resume). For FTP, set this +option to -1 to make the transfer start from the end of the target file +(useful to continue an interrupted upload). + +When doing uploads with FTP, the resume position is where in the local/source +file libcurl should try to resume the upload from and it will then append the +source file to the remote target file. + +If you need to resume a transfer beyond the 2GB limit, use +\fICURLOPT_RESUME_FROM_LARGE(3)\fP instead. +.SH DEFAULT +0, not used +.SH PROTOCOLS +HTTP, FTP, SFTP, FILE +.SH EXAMPLE +.nf +CURL *curl = curl_easy_init(); +if(curl) { + curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com"); + + /* resume upload at byte index 200 */ + curl_easy_setopt(curl, CURLOPT_RESUME_FROM, 200L); + + /* ask for upload */ + curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L); + + /* set total data amount to expect */ + curl_easy_setopt(curl, CURLOPT_INFILESIZE, size_of_file); + + /* Perform the request */ + curl_easy_perform(curl); +} +.fi +.SH AVAILABILITY +Always +.SH RETURN VALUE +Returns CURLE_OK +.SH "SEE ALSO" +.BR CURLOPT_RESUME_FROM_LARGE "(3), " CURLOPT_RANGE "(3), " +.BR CURLOPT_INFILESIZE "(3), " |
