GNURLOPT_KRBLEVEL(3)

🎀 GNURLOPT_KRBLEVEL(3) 🎀

okay so bestie, welcome to the curl_easy_setopt options manual page for GNURLOPT_KRBLEVEL(3). it’s the FTP kerberos security level option, and it’s lowkey iconic. 💅✨

💖 NAME 💖

CURLOPT_KRBLEVEL - set FTP kerberos security level

✨ SYNOPSIS ✨

#include <gnurl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_KRBLEVEL, char *level);

🦋 DESCRIPTION 🦋

Pass a char * as parameter. Set the kerberos security level for FTP; this also enables kerberos awareness.

This is a string that should match one of the following: clear, safe, confidential or private. If the string is set but doesn't match one of these, private will be used. Set the string to NULL to disable kerberos support for FTP.

The application does not have to keep the string around after setting this option. 🫶 so yes, you can set it and move on — no string babysitting required.

🎀 DEFAULT 🎀

NULL
