CURLOPT_RESUME_FROM_LARGE 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
NAME
CURLOPT_RESUME_FROM_LARGE - set a point to resume transfer from
SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM_LARGE, curl_off_t from);DESCRIPTIONPass a curl_off_t as parameter. 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.DEFAULT0, not usedPROTOCOLSHTTP, FTP, SFTP, FILEEXAMPLECURL *curl = curl_easy_init(); if(curl) { curl_off_t resume_position = GET_IT_SOMEHOW; curl_off_t file_size = GET_IT_SOMEHOW_AS_WELL; curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com"); /* resuming upload at this position, possibly beyond 2GB */ curl_easy_setopt(curl, CURLOPT_RESUME_FROM_LARGE, resume_position); /* ask for upload */ curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L); /* set total data amount to expect */ curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, file_size); /* Perform the request */ curl_easy_perform(curl); }AVAILABILITYAdded in 7.11.0RETURN VALUEReturns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not."SEE ALSO"CURLOPT_RESUME_FROM "(3), " CURLOPT_RANGE "(3), " CURLOPT_INFILESIZE_LARGE "(3), "
