UPSCLI_CONNECT(3) ================= NAME ---- upscli_connect - Open a connection to a NUT upsd SYNOPSIS -------- #include 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 linkman: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.
