# UPSCLI_SSL(3)

## NAME

upscli_ssl - Check SSL mode for current connection

## SYNOPSIS

            #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.
