Function Documentation

LE_MEM_DEFINE_STATIC_POOL()

LE_MEM_DEFINE_STATIC_POOL	(	taf_diagSecurity_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)

)

Return the sessionRef for the current thread.

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

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.

taf_diagSecurity_ConnectService()

void taf_diagSecurity_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.

taf_diagSecurity_TryConnectService()

le_result_t taf_diagSecurity_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

taf_diagSecurity_SetServerDisconnectHandler()

void taf_diagSecurity_SetServerDisconnectHandler	(	taf_diagSecurity_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

taf_diagSecurity_SetNonExitServerDisconnectHandler()

void taf_diagSecurity_SetNonExitServerDisconnectHandler	(	taf_diagSecurity_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.

taf_diagSecurity_DisconnectService()

void taf_diagSecurity_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.

taf_diagSecurity_GetService()
