enum Gio::DBus::Error::Code

Error codes for the G_DBUS_ERROR error domain.

Since glibmm 2.26:

Enumerator
FAILED	A generic error; "something went wrong" - see the error message for more.
NO_MEMORY	There was not enough memory to complete an operation.
SERVICE_UNKNOWN	The bus doesn't know how to launch a service to supply the bus name you wanted.
NAME_HAS_NO_OWNER	The bus name you referenced doesn't exist (i.e. no application owns it).
NO_REPLY	No reply to a message expecting one, usually means a timeout occurred.
IO_ERROR	Something went wrong reading or writing to a socket, for example.
BAD_ADDRESS	A D-Bus bus address was malformed.
NOT_SUPPORTED	Requested operation isn't supported (like ENOSYS on UNIX).
LIMITS_EXCEEDED	Some limited resource is exhausted.
ACCESS_DENIED	Security restrictions don't allow doing what you're trying to do.
AUTH_FAILED	Authentication didn't work.
NO_SERVER	Unable to connect to server (probably caused by ECONNREFUSED on a socket).
TIMEOUT	Certain timeout errors, possibly ETIMEDOUT on a socket. Note that Gio::DBus::Error::NO_REPLY is used for message reply timeouts. Warning: this is confusingly-named given that Gio::DBus::Error::TIMED_OUT also exists. We can't fix it for compatibility reasons so just be careful.
NO_NETWORK	No network access (probably ENETUNREACH on a socket).
ADDRESS_IN_USE	Can't bind a socket since its address is in use (i.e. EADDRINUSE).
DISCONNECTED	The connection is disconnected and you're trying to use it.
INVALID_ARGS	Invalid arguments passed to a method call.
FILE_NOT_FOUND	Missing file.
FILE_EXISTS	Existing file and the operation you're using does not silently overwrite.
UNKNOWN_METHOD	Method name you invoked isn't known by the object you invoked it on.
TIMED_OUT	Certain timeout errors, e.g. while starting a service. Warning: this is confusingly-named given that Gio::DBus::Error::TIMEOUT also exists. We can't fix it for compatibility reasons so just be careful.
MATCH_RULE_NOT_FOUND	Tried to remove or modify a match rule that didn't exist.
MATCH_RULE_INVALID	The match rule isn't syntactically valid.
SPAWN_EXEC_FAILED	While starting a new process, the exec() call failed.
SPAWN_FORK_FAILED	While starting a new process, the fork() call failed.
SPAWN_CHILD_EXITED	While starting a new process, the child exited with a status code.
SPAWN_CHILD_SIGNALED	While starting a new process, the child exited on a signal.
SPAWN_FAILED	While starting a new process, something went wrong.
SPAWN_SETUP_FAILED	We failed to setup the environment correctly.
SPAWN_CONFIG_INVALID	We failed to setup the config parser correctly.
SPAWN_SERVICE_INVALID	Bus name was not valid.
SPAWN_SERVICE_NOT_FOUND	Service file not found in system-services directory.
SPAWN_PERMISSIONS_INVALID	Permissions are incorrect on the setuid helper.
SPAWN_FILE_INVALID	Service file invalid (Name, User or Exec missing).
SPAWN_NO_MEMORY	Tried to get a UNIX process ID and it wasn't available.
UNIX_PROCESS_ID_UNKNOWN	Tried to get a UNIX process ID and it wasn't available.
INVALID_SIGNATURE	A type signature is not valid.
INVALID_FILE_CONTENT	A file contains invalid syntax or is otherwise broken.
SELINUX_SECURITY_CONTEXT_UNKNOWN	Asked for SELinux security context and it wasn't available.
ADT_AUDIT_DATA_UNKNOWN	Asked for ADT audit data and it wasn't available.
OBJECT_PATH_IN_USE	There's already an object with the requested object path.
UNKNOWN_OBJECT	Object you invoked a method on isn't known. Since glibmm 2.42:
UNKNOWN_INTERFACE	Interface you invoked a method on isn't known by the object. Since glibmm 2.42:
UNKNOWN_PROPERTY	Property you tried to access isn't known by the object. Since glibmm 2.42:
PROPERTY_READ_ONLY	Property you tried to set is read-only. Since glibmm 2.42:
