CURLOPT_R...FROM_LARGE(3)  Library Functions Manual  CURLOPT_R...FROM_LARGE(3)

NAME
       CURLOPT_RESUME_FROM_LARGE - offset to resume transfer from

SYNOPSIS
       #include	<curl/curl.h>

       CURLcode	curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM_LARGE,
				 curl_off_t from);

DESCRIPTION
       Pass  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  re-
       sume).  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  lo-
       cal/source file libcurl should try to resume the	upload from and	it ap-
       pends the source	file to	the remote target file.

DEFAULT
       0, not used

PROTOCOLS
       This functionality affects all supported	protocols

EXAMPLE
       int main(void)
       {
	 CURL *curl = curl_easy_init();
	 if(curl) {
	   curl_off_t resume_position =	1234; /* get it	somehow	*/
	   curl_off_t file_size	= 9876;	/* 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);
	 }
       }
