◆ LE_MEM_DEFINE_STATIC_POOL()

LE_MEM_DEFINE_STATIC_POOL	(	le_appCtrl_ClientThreadData	,
		LE_CDATA_COMPONENT_COUNT	,
		sizeof(_ClientThreadData_t)
	)

Static pool for client threads.

◆ InitClientForThread()

static le_result_t InitClientForThread ( bool isBlocking )

static

Initialize thread specific data, and connect to the service for the current thread.

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.

◆ GetClientThreadDataPtr()

static _ClientThreadData_t* GetClientThreadDataPtr ( void )

static

Get a pointer to the client thread data for the current thread.

If the current thread does not have client data, then NULL is returned

◆ attribute()

__attribute__ ( (unused) )

[in] Not used

[in] Reference to the message.

Return the sessionRef for the current thread.

If the current thread does not have a session ref, then this is a fatal error.

Cleanup client data if the client is no longer connected

Send the message to the client (queued version)

This is a wrapper around le_msg_Send() with an extra parameter so that it can be used with le_event_QueueFunctionToThread().

Send the message to the client.

◆ ClientThreadDestructor()

static void ClientThreadDestructor ( void * objPtr )

static

Destructor function for client thread objects.

◆ InitCommonData()

static void InitCommonData ( void )

static

Init data that is common across all threads.

◆ DoConnectService()

static le_result_t DoConnectService ( bool isBlocking )

static

Connect to the service, using either blocking or non-blocking calls.

This function implements the details of the public ConnectService functions.

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.

◆ le_appCtrl_ConnectService()

void le_appCtrl_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 apiFilesC_client.

This function is created automatically.

◆ le_appCtrl_TryConnectService()

le_result_t le_appCtrl_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 apiFilesC_client.

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.

◆ SessionCloseHandler()

static void SessionCloseHandler	(	le_msg_SessionRef_t	sessionRef,
		void *	contextPtr
	)

static

◆ le_appCtrl_SetServerDisconnectHandler()

void le_appCtrl_SetServerDisconnectHandler	(	le_appCtrl_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.

◆ NonExitSessionCloseHandler()

static void NonExitSessionCloseHandler	(	le_msg_SessionRef_t	sessionRef,
		void *	contextPtr
	)

static

◆ le_appCtrl_SetNonExitServerDisconnectHandler()

void le_appCtrl_SetNonExitServerDisconnectHandler	(	le_appCtrl_DisconnectHandler_t	disconnectHandler,
		void *	contextPtr
	)

Set handler called when server disconnection is detected without exiting.

When a server connection is lost, call this handler without exit.

Warning: When using the API, it needs the application developer to handle some cases like re-connecting and recycling the resources. For most of cases, it is safe to use SetServerDisconnectHandler.

◆ le_appCtrl_DisconnectService()

void le_appCtrl_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 apiFilesC_client.

This function is created automatically.

◆ le_appCtrl_GetRef()

◆ le_appCtrl_ReleaseRef()

void le_appCtrl_ReleaseRef ( le_appCtrl_AppRef_t appRef )

◆ le_appCtrl_SetRun()

void le_appCtrl_SetRun	(	le_appCtrl_AppRef_t	appRef,
		const char *LE_NONNULL	procName,
