EPC_DEBUG_LEVEL()

#define EPC_DEBUG_LEVEL(level) G_UNLIKELY(epc_shell_get_debug_level () >= (level))

Checks if the library's debug level, which can be modified by setting the EPC_DEBUG environment variable, is above the value sepecified by level .

epc_shell_get_debug_level ()

guint
epc_shell_get_debug_level (void);

Query the library's debug level. The debug level can be modified by setting the external EPC_DEBUG environment variable. In most cases the EPC_DEBUG_LEVEL macro should be used, instead of calling this checking the return value of this function.

epc_shell_progress_begin ()

void
epc_shell_progress_begin (const gchar *title,
                          const gchar *message);

Call this function before starting a lengthy operation to allow the application tp provide some visual feedback during the operation, and to generally keep its UI responsive.

This function calls your “begin” hook with title as argument and “update” with message .

epc_shell_progress_end ()

void
epc_shell_progress_end (void);

Call this function when your lengthy operation has finished.

epc_shell_progress_update ()

void
epc_shell_progress_update (gdouble percentage,
                           const gchar *message);

Called this function to inform about progress of a lengthy operation. The progress is expressed as percentage in the range [0..1], or -1 if the progress cannot be estimated.

epc_shell_set_progress_hooks ()

void
epc_shell_set_progress_hooks (const EpcShellProgressHooks *hooks,
                              gpointer user_data,
                              GDestroyNotify destroy_data);

Installs functions which are called during processing, such as generating server keys. This allows the application to indicate progress and generally keep its UI responsive. If no progress callbacks are provided, or when NULL is passed for hooks , progress messages are written to the console.

epc_shell_watch_avahi_client_state ()

guint
epc_shell_watch_avahi_client_state (AvahiClientCallback callback,
                                    gpointer user_data,
                                    GDestroyNotify destroy_data,
                                    GError **error);

Registers a function to watch state changes of the library's AvahiClient. On success the identifier of the newly created watch is returned. Pass it to epc_shell_watch_remove() to remove the watch. On failure it returns 0 and sets error . The error domain is EPC_AVAHI_ERROR. Possible error codes are those of the Avahi library.

epc_shell_create_avahi_entry_group ()

AvahiEntryGroup *
epc_shell_create_avahi_entry_group (AvahiEntryGroupCallback callback,
                                    gpointer user_data);

Creates a new AvahiEntryGroup for the library's shared AvahiClient. On success the newly created AvahiEntryGroup is returned, and NULL on failure.

epc_shell_create_service_browser ()

AvahiServiceBrowser *
epc_shell_create_service_browser (AvahiIfIndex interface,
                                  AvahiProtocol protocol,
                                  const gchar *type,
                                  const gchar *domain,
                                  AvahiLookupFlags flags,
                                  AvahiServiceBrowserCallback callback,
                                  gpointer user_data,
                                  GError **error);

Creates a new AvahiServiceBrowser for the library's shared AvahiClient. On success the newly created AvahiEntryGroup is returned. On failure NULL is returned and error is set. The error domain is EPC_AVAHI_ERROR. Possible error codes are those of the Avahi library.

epc_shell_restart_avahi_client ()

void
epc_shell_restart_avahi_client (const gchar *strloc);

Requests restart of the builtin Avahi client. Use this function to react on critical failures (like AVAHI_ENTRY_GROUP_FAILURE) reported to your Avahi callbacks. The strloc argument is used to prevent endless restart cycles.

epc_shell_get_host_name ()

const gchar *
epc_shell_get_host_name (GError **error);

Retrieves the official host name of this machine. On failure the function returns NULL and sets error . The error domain is EPC_AVAHI_ERROR. Possible error codes are those of the Avahi library.

epc_shell_watch_remove ()

void
epc_shell_watch_remove (guint id);

Removes the watching callback identified by id .

This table is used by epc_shell_set_progress_hooks to install functions allowing the library to provide feedback during processing.

EPC_AVAHI_ERROR

#define EPC_AVAHI_ERROR (epc_avahi_error_quark ())

Error domain for Avahi operations. Errors in this domain will be Avahi error codes. See GError for information on error domains.
