Typedef Documentation

◆ le_posCtrl_DisconnectHandler_t

typedef void(* le_posCtrl_DisconnectHandler_t) (void *)

Type for handler called when a server disconnects.

Function Documentation

◆ le_posCtrl_ConnectService()

void le_posCtrl_ConnectService ( void  )

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.

◆ le_posCtrl_DisconnectService()

void le_posCtrl_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.

◆ le_posCtrl_Release()

void le_posCtrl_Release ( le_posCtrl_ActivationRef_t  ref)

Release the positioning service.

Parameters
[in]refReference to a positioning service activation request.

◆ le_posCtrl_Request()

le_posCtrl_ActivationRef_t le_posCtrl_Request ( void  )

Reference type for dealing with Position Service management. Request activation of the positioning service.

Returns
  • Reference to the service activation request (to be used later for releasing the request).
  • NULL if the service request could not be processed.

◆ le_posCtrl_SetServerDisconnectHandler()

LE_FULL_API void le_posCtrl_SetServerDisconnectHandler ( le_posCtrl_DisconnectHandler_t  disconnectHandler,
void *  contextPtr 
)

Set handler called when server disconnection is detected.

When a server connection is lost, call this handler then exit with LE_FATAL. If a program wants to continue without exiting, it should call longjmp() from inside the handler.

◆ le_posCtrl_TryConnectService()

le_result_t le_posCtrl_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.
