NAME

CURLOPT_CRLF - CRLF conversion

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CRLF, long conv);

DESCRIPTION

Pass a long. If the value is set to 1 (one), libcurl converts Unix newlines to CRLF newlines on transfers. Disable this option again by setting the value to 0 (zero).

This is a legacy option of questionable use.

DEFAULT

0
