## Types and Values

### enum NMAgentManagerError

Errors returned from the secret-agent manager.

These errors may be returned from operations that could cause secrets to be requested (such as `nm_client_activate_connection()`), and correspond to D-Bus errors in the "org.freedesktop.NetworkManager.AgentManager" namespace.

#### Members

NM_AGENT_MANAGER_ERROR_FAILED | unknown or unspecified error |
NM_AGENT_MANAGER_ERROR_PERMISSION_DENIED | The caller does not have permission to register a secret agent, or is trying to register the same secret agent twice. |
NM_AGENT_MANAGER_ERROR_INVALID_IDENTIFIER | The identifier is not a valid secret agent identifier. |
NM_AGENT_MANAGER_ERROR_NOT_REGISTERED | The caller tried to unregister an agent that was not registered. |
NM_AGENT_MANAGER_ERROR_NO_SECRETS | No secret agent returned secrets for this request |
NM_AGENT_MANAGER_ERROR_USER_CANCELED | The user canceled the secrets request. |

### NM_AGENT_MANAGER_ERROR

    #define NM_AGENT_MANAGER_ERROR (nm_agent_manager_error_quark())

### enum NMConnectionError

Describes errors that may result from operations involving a NMConnection or its NMSettings.

These errors may be returned directly from NMConnection and NMSetting methods, or may be returned from D-Bus operations (eg on NMClient or NMDevice), where they correspond to errors in the "org.freedesktop.NetworkManager.Settings.Connection" namespace.

#### Members

NM_CONNECTION_ERROR_FAILED | unknown or unclassified error |
NM_CONNECTION_ERROR_SETTING_NOT_FOUND | the NMConnection object did not contain the specified NMSetting object |
NM_CONNECTION_ERROR_PROPERTY_NOT_FOUND | the NMConnection did not contain the requested NMSetting property |
NM_CONNECTION_ERROR_PROPERTY_NOT_SECRET | an operation which requires a secret was attempted on a non-secret property |
NM_CONNECTION_ERROR_MISSING_SETTING | the NMConnection object is missing an NMSetting which is required for its configuration. The error message will always be prefixed with "<setting-name>: ", where "<setting-name>" is the name of the setting that is missing. |
NM_CONNECTION_ERROR_INVALID_SETTING | the NMConnection object contains an invalid or inappropriate NMSetting. The error message will always be prefixed with "<setting-name>: ", where "<setting-name>" is the name of the setting that is invalid. |
NM_CONNECTION_ERROR_MISSING_PROPERTY | the NMConnection object is invalid because it is missing a required property. The error message will always be prefixed with "<setting-name>.<property-name>: ", where "<setting-name>" is the name of the setting with the missing property, and "<property-name>" is the property that is missing. |
NM_CONNECTION_ERROR_INVALID_PROPERTY | the NMConnection object is invalid because a property has an invalid value. The error message will always be prefixed with "<setting-name>.<property-name>: ", where "<setting-name>" is the name of the setting with the invalid property, and "<property-name>" is the property that is invalid. |

### NM_DEVICE_ERROR

    #define NM_DEVICE_ERROR nm_device_error_quark()

### enum NMManagerError

Errors related to the main "network management" interface of NetworkManager. These may be returned from NMClient methods that invoke D-Bus operations on the "org.freedesktop.NetworkManager" interface, and correspond to D-Bus errors in that namespace.

#### Members

NM_MANAGER_ERROR_FAILED | unknown or unclassified error |
NM_MANAGER_ERROR_PERMISSION_DENIED | Permission denied. |
NM_MANAGER_ERROR_UNKNOWN_CONNECTION | The requested connection is not known. |
NM_MANAGER_ERROR_UNKNOWN_DEVICE | The requested device is not known. |
NM_MANAGER_ERROR_CONNECTION_NOT_AVAILABLE | The requested connection cannot be activated at this time. |

### NM_MANAGER_ERROR

    #define NM_MANAGER_ERROR (nm_manager_error_quark())

### enum NMSecretAgentError

NMSecretAgentError values are passed by secret agents back to NetworkManager when they encounter problems retrieving secrets on behalf of NM. They correspond to errors in the "org.freedesktop.NetworkManager.SecretManager" namespace.

Client APIs such as `nm_client_activate_connection()` will not see these error codes; instead, the secret agent manager will translate them to the corresponding NMAgentManagerError codes.

#### Members

NM_SECRET_AGENT_ERROR_AGENT_CANCELED | the agent canceled the request because it was requested to do so by NetworkManager |
NM_SECRET_AGENT_ERROR_NO_SECRETS | the agent cannot find any secrets for this connection |

### NM_SECRET_AGENT_ERROR

    #define NM_SECRET_AGENT_ERROR (nm_secret_agent_error_quark())

### enum NMSettingsError

Errors related to the settings/persistent configuration interface of NetworkManager.

These may be returned from NMClient methods that invoke D-Bus operations on the "org.freedesktop.NetworkManager.Settings" interface, and correspond to D-Bus errors in that namespace.

#### Members
