CURLOPT_CRLF(3) Library Functions Manual CURLOPT_CRLF(3) NAME CURLOPT_CRLF - CRLF conversion SYNOPSIS #include 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 PROTOCOLS This functionality affects all supported protocols EXAMPLE 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); } } AVAILABILITY Added in curl 7.1 RETURN VALUE curl_easy_setopt(3) returns a CURLcode indicating success or error.
