Note
Two NUT websites

This version of the page reflects NUT release v2.8.5 with codebase commited 0e051f9f6 at 2026-04-07T11:40:11+02:00

Options, features and capabilities in current development (and future releases) are detailed on the main site and may differ from ones described here.

 
        #include <upsclient.h>

        int upscli_ssl(UPSCONN_t *ups);

DESCRIPTION

The upscli_ssl() function takes the pointer ups to a UPSCONN_t state structure. It only returns 1 if SSL support has been compiled into the upsclient(3) library, and if it was successfully enabled for this connection.

Starting with NUT v2.8.5, you can use upscli_ssl_caps(3) from consumer code to query the library about its build circumstances (whether it supports SSL, and which backend(s)).

RETURN VALUE

The upscli_ssl() function returns 1 if SSL is running, and 0 if not. It returns -1 in the event of an error.
