UPSCLI_CONNECT(3)                 NUT Manual                 UPSCLI_CONNECT(3)

NAME
       upscli_connect - Open a connection to a NUT upsd

SYNOPSIS
       #include <upsclient.h>

       int upscli_connect(UPSCONN_t *ups, const char *host, int port, int flags);

DESCRIPTION
       The upscli_connect() function takes the pointer ups to a UPSCONN_t
       state structure and opens a TCP connection to the host on the given
       port.

       flags may be either UPSCLI_CONN_TRYSSL to try a SSL connection, or
       UPSCLI_CONN_REQSSL to require a SSL connection.

       If SSL mode is required, this function will only return successfully if
       it is able to establish a SSL connection with the server. Possible
       reasons for failure include no SSL support on the server, and if
       upsclient itself hasn't been compiled with SSL support.

       You must call upscli_disconnect(3) when finished with a connection, or
       your program will slowly leak memory and file descriptors.

RETURN VALUE
       The upscli_connect() function modifies the UPSCONN_t structure and
       returns 0 on success, or -1 if an error occurs.
