.TH CURLOPT_RANGE 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_RANGE \- set byte range to request
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RANGE, char *range);
.SH 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
\fI"X-Y,N-M"\fP. 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 \fBnot\fP permitted. Instead, ranges should
be given in npt, utc, or smpte formats.
Pass a NULL to this option to disable the use of ranges.
