7 upscli_connect - Open a connection to a NUT upsd
12 #include <upsclient.h>
14 int upscli_connect(UPSCONN_t *ups, const char *host, int port, int flags);
18 The *upscli_connect()* function takes the pointer 'ups' to a
19 `UPSCONN_t` state structure and opens a TCP connection to the 'host' on
22 'flags' may be either `UPSCLI_CONN_TRYSSL` to try a SSL
23 connection, or `UPSCLI_CONN_REQSSL` to require a SSL connection.
25 If SSL mode is required, this function will only return successfully if
26 it is able to establish a SSL connection with the server. Possible
27 reasons for failure include no SSL support on the server, and if
28 *upsclient* itself hasn't been compiled with SSL support.
30 You must call linkman:upscli_disconnect[3] when finished with a
31 connection, or your program will slowly leak memory and file
37 The *upscli_connect()* function modifies the `UPSCONN_t` structure and
38 returns 0 on success, or -1 if an error occurs.
