Returns : | a list of NMConnection objects that could be activated with the given `device`.

[transfer container][element-type NMConnection]

### nm_device_connection_valid ()

    gboolean            nm_device_connection_valid          (NMDevice *device,

Validates a given connection for a given NMDevice object and returns whether the connection may be activated with the device. For example if `device` is a Wi-Fi device that supports only WEP encryption, the connection will only be valid if it is a Wi-Fi connection which describes a WEP or open network, and will not be valid if it describes a WPA network, or if it is an Ethernet, Bluetooth, WWAN, etc connection that is incompatible with the device.

Validates a given connection for a given NMDevice object and returns whether the connection may be activated with the device. For example if `device` is a Wi-Fi device that supports only WEP encryption, the connection will only be valid if it is a Wi-Fi connection which describes a WEP or open network, and will not be valid if it describes a WPA network, or if it is an Ethernet, Bluetooth, WWAN, etc connection that is incompatible with the device.

This function does the same as `nm_device_connection_valid()`, i.e. checking compatibility of the given device and connection. But, in addition, it sets GError when FALSE is returned.

`device` : | an NMDevice to validate `connection` against
`connection` : | an NMConnection to validate against `device`
`error` : | return location for a GError, or `NULL`
Returns : | `TRUE` if the connection may be activated with this device, `FALSE` if is incompatible with the device's capabilities and characteristics.
