This may be useful for determining if the connection to upsd(8) has been lost. Return Value…
upscli_disconnect – disconnect from a UPS server Synopsis #include <upsclient.h> int upscli_disconnect(UPSCONN_t *ups); Description The upscli_disconnect() function takes the pointer ups to a UPSCONN_t state structure, shuts down the connection to the server, and frees dynamic memory used by the state structure. The UPSCONN_t structure is no longer valid after this function is called. This…
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…
upscli_cleanup – Clean-up upsclient module after usage. Synopsis #include <upsclient.h> int upscli_cleanup(); Description The upscli_cleanup() function flushes SSL caches and frees memory used internally in upsclient module. Return Value The upscli_cleanup() function returns 1 on success, or -1 if an error occurs. See Also upscli_init(3), upscli_strerror(3), upscli_upserror(3)
upscli_add_host_cert – Register a security rule for an host. Synopsis #include <upsclient.h> void upscli_add_host_cert(const char *hostname, const char *certname, int certverify, int forcessl); Description The upscli_add_host_cert() function register a security rule associated to the hostname. All connections to this host use this rule. The rule is composed of the certificate name certname ‘expected for the…
