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).
|
the GError given from the remote method |
|
the D-BUS error name |
Returns : |
TRUE iff the remote error has the given 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.
|
the GError given from the remote method |
Returns : |
the D-BUS name for a remote exception. |
GQuark dbus_g_error_quark (void);
The implementation of DBUS_GERROR error domain. See documentation for GError in GLib reference manual.
Returns : |
the error domain quark for use with GError |
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.)
