## Implemented Interfaces

MMModemSignal implements GDBusInterface, GInitable, GAsyncInitable and MmGdbusModemSignal.

## Description

The MMModemSignal is an object providing access to the methods, signals and properties of the Signal interface.

The Signal interface is exposed whenever a modem has extended signal retrieval capabilities.

## Functions

### mm_modem_signal_get_path ()

    const gchar *
    mm_modem_signal_get_path (MMModemSignal *self);

Gets the DBus path of the MMObject which implements this interface.

#### Parameters

self | A MMModemSignal. |

#### Returns

The DBus path of the MMObject object.

[transfer none]

Since: 1.2

### mm_modem_signal_dup_path ()

    gchar *
    mm_modem_signal_dup_path (MMModemSignal *self);

Gets a copy of the DBus path of the MMObject object which implements this interface.

#### Parameters

self | A MMModemSignal. |

#### Returns

The DBus path of the MMObject. The returned value should be freed with `g_free()`.

### mm_modem_signal_get_rate ()

    guint
    mm_modem_signal_get_rate (MMModemSignal *self);

Gets the currently configured refresh rate.

#### Parameters

### mm_modem_signal_peek_cdma ()

    MMSignal *
    mm_modem_signal_peek_cdma (MMModemSignal *self);

Gets a MMSignal object specifying the CDMA signal information.

The returned value is only valid until the property changes so it is only safe to use this function on the thread where `self` was constructed. Use `mm_modem_signal_get_cdma()` if on another thread.

#### Parameters

self | A MMModem. |

#### Returns

thread-default main loop

of the thread you are calling this method from. You can then call `mm_modem_signal_setup_finish()` to get the result of the operation.

See `mm_modem_signal_setup_sync()` for the synchronous, blocking version of this method.

#### Parameters

self | A MMModemSignal. |
rate | Rate to use when refreshing signal values. |
cancellable | A GCancellable or `NULL`. | [allow-none]
callback | A GAsyncReadyCallback to call when the request is satisfied or `NULL`. |
