NAME
CURLOPT_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 follow 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.
EXAMPLE

if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

/* Perform the request */
curl_easy_perform(curl);
}
