dbus_g_error_has_name ()

gboolean
dbus_g_error_has_name (GError *error,
                       const char *name);

Determine whether D-BUS error name for a remote exception matches the given name. This function is intended to be invoked on a GError returned from an invocation of a remote method, e.g. via dbus_g_proxy_end_call(). It will silently return FALSE for errors which are not remote D-BUS exceptions (i.e. with a domain other than DBUS_GERROR or a code other than DBUS_GERROR_REMOTE_EXCEPTION).

dbus_g_error_get_name ()

const char *
dbus_g_error_get_name (GError *error);

This function may only be invoked on a GError returned from an invocation of a remote method, e.g. via dbus_g_proxy_end_call(). Moreover, you must ensure that the error's domain is DBUS_GERROR, and the code is DBUS_GERROR_REMOTE_EXCEPTION.

dbus_g_error_domain_register ()

void
dbus_g_error_domain_register (GQuark domain,
                              const char *default_iface,
                              GType code_enum);

Register a GError domain and set of codes with D-Bus. When an object raises a GError in the domain domain from one of its D-Bus methods, the D-Bus error name used will be default_iface , followed by a dot, followed by the GEnumValue.value_nick corresponding to the GError.code. For D-Bus, it's conventional to use an error name (value_nick) that is in CamelCase.

(For instance, if a D-Bus method com.example.MyObject.GetThings can raise a GError with domain MY_ERROR and code

MY_ERROR_NOT_HAPPY, you could call dbus_g_error_domain_register (MY_ERROR, "com.example.MyError", MY_TYPE_ERROR), and set up the value_nick for MY_ERROR_NOT_HAPPY to be NotHappy,

resulting in the D-Bus error string

com.example.MyError.NotHappy.)

If default_iface is NULL, the D-Bus interface of the method that failed will be used.

(For instance, if the above example had called

dbus_g_error_domain_register (MY_ERROR, NULL, MY_TYPE_ERROR)

instead, then the D-Bus error string would be

com.example.MyObject.NotHappy.)

enum DBusGError

A GError enumeration for the domain DBUS_GERROR. The values' meanings can be found by looking at the comments for the corresponding constants in dbus-protocol.h.

DBUS_GERROR

#define DBUS_GERROR dbus_g_error_quark ()

Expands to a function call returning the error domain quark for DBusGError, for use with GError.
