Function Documentation

void le_wdog_ConnectService ( void  )

Special values that have specific meaning when used as durations in Timeout():

Connect the current client thread to the service providing this API. Block until the service is available.

For each thread that wants to use this API, either ConnectService or TryConnectService must be called before any other functions in this API. Normally, ConnectService is automatically called for the main thread, but not for any other thread. For details, see Client-specific Functions.

This function is created automatically.

void le_wdog_DisconnectService ( void  )

Disconnect the current client thread from the service providing this API.

Normally, this function doesn't need to be called. After this function is called, there's no longer a connection to the service, and the functions in this API can't be used. For details, see Client-specific Functions.

This function is created automatically.

void le_wdog_Kick ( void  )

Kicks the watchdog timer.

Once the watchdog has been kicked it must be kicked again before the expiration of the current effective timeout else the configured WatchdogAction will be executed.

void le_wdog_Timeout ( int32_t  milliseconds)

Set a time out.

The watchdog is kicked and a new effective timeout value is set. The new timeout will be effective until the next kick at which point it will revert to the original value.

Parameters
[in]millisecondsThe number of milliseconds until this timer expires
le_result_t le_wdog_TryConnectService ( void  )

Try to connect the current client thread to the service providing this API. Return with an error if the service is not available.

For each thread that wants to use this API, either ConnectService or TryConnectService must be called before any other functions in this API. Normally, ConnectService is automatically called for the main thread, but not for any other thread. For details, see Client-specific Functions.

This function is created automatically.

Returns
  • LE_OK if the client connected successfully to the service.
  • LE_UNAVAILABLE if the server is not currently offering the service to which the client is bound.
  • LE_NOT_PERMITTED if the client interface is not bound to any service (doesn't have a binding).
  • LE_COMM_ERROR if the Service Directory cannot be reached.
