CURLOPT_CRLF - CRLF conversion

Added in curl 7.1

0

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.

int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode ret; curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/"); curl_easy_setopt(curl, CURLOPT_CRLF, 1L); ret = curl_easy_perform(curl); curl_easy_cleanup(curl); } }
