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). Unfortunately, the HTTP standard (RFC 7233 section 3.1)  allows  servers  to
       ignore  range  requests so even when you set CURLOPT_RANGE for a request, you may end up getting the full
       response sent back.

       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

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

         /* get the first 200 bytes */
         curl_easy_setopt(curl, CURLOPT_RANGE, "0-199");

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

AVAILABILITY

       FILE since 7.18.0, RTSP since 7.20.0

RETURN VALUE

       Returns CURLE_OK on success or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
