CURLOPT_RESUME_FROM(3)					     curl_easy_setopt options					    CURLOPT_RESUME_FROM(3)

NAME

       CURLOPT_RESUME_FROM - set a point to resume transfer from

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM, long from);

DESCRIPTION

       Pass  a long 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.

       If you need to resume a transfer beyond the 2GB limit, use CURLOPT_RESUME_FROM_LARGE(3) instead.

	 curl_easy_setopt(curl, CURLOPT_RESUME_FROM, 200L);

	 /* ask for upload */
