CURLOPT_RANGE(3) curl_easy_setopt options CURLOPT_RANGE(3)NAMECURLOPT_RANGE - set byte range to request
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RANGE, char *range);
DESCRIPTION
Pass a char * as parameter, which should contain the specified range
you want to retrieve. It should be in the format "X-Y", where either X
or Y may be left out and X and Y are byte indexes.
HTTP transfers also support several intervals, separated with commas as
in "X-Y,N-M". Using this kind of multiple intervals will cause the HTTP
server to send the response document in pieces (using standard MIME
separation techniques). For RTSP, the formatting of a range should fol‐
low RFC2326 Section 12.29. For RTSP, byte ranges are not permitted.
Instead, ranges should be given in npt, utc, or smpte formats.
Pass a NULL to this option to disable the use of ranges.
DEFAULT
NULL
PROTOCOLS
HTTP, FTP, FILE, RTSP and SFTP.

/* Perform the request */

}
