UPSCLI_FD(3) NUT Manual UPSCLI_FD(3)NAME
upscli_fd - Get file descriptor for connection
SYNOPSIS
#include <upsclient.h>
int upscli_fd(UPSCONN_t *ups);
DESCRIPTION
The upscli_fd() function takes the pointer ups to a UPSCONN_t state structure and returns the value of the file descriptor for that
connection, if any.
This may be useful for determining if the connection to upsd(8) has been lost.
RETURN VALUE
The upscli_fd() function returns the file descriptor, which may be any non-negative number. It returns -1 if an error occurs.

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.
