◆ LE_MEM_DEFINE_STATIC_POOL()

LE_MEM_DEFINE_STATIC_POOL	(	le_cfgAdmin_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.

◆ le_cfgAdmin_ConnectService()

void le_cfgAdmin_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_cfgAdmin_TryConnectService()

le_result_t le_cfgAdmin_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_cfgAdmin_SetServerDisconnectHandler()

void le_cfgAdmin_SetServerDisconnectHandler	(	le_cfgAdmin_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_cfgAdmin_SetNonExitServerDisconnectHandler()

void le_cfgAdmin_SetNonExitServerDisconnectHandler	(	le_cfgAdmin_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_cfgAdmin_DisconnectService()

void le_cfgAdmin_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_cfgAdmin_ImportTree()

le_result_t le_cfgAdmin_ImportTree	(	le_cfg_IteratorRef_t	iteratorRef,
		const char *LE_NONNULL	filePath,
		const char *LE_NONNULL	nodePath
	)

Read a subset of the configuration tree from the given filePath. The tree then overwrites the node at the given nodePath.

This function will import a sub-tree as part of the iterator's current transaction. This allows you to create an iterator on a given node. Import a sub-tree, and then examine the contents of the import before deciding to commit the new data.

Returns

This function will return one of the following values:

    - LE_OK            - The commit was completed successfuly.
    - LE_FAULT         - An I/O error occured while reading the data.
    - LE_FORMAT_ERROR  - The configuration data being imported appears corrupted.

Parameters

[in]	iteratorRef	Write iterator that is being used for the import.
[in]	filePath	Import the tree data from the this file.
[in]	nodePath	Where in the tree should this import happen? Leave as an empty string to use the iterator's current node.

◆ le_cfgAdmin_ExportTree()

le_result_t le_cfgAdmin_ExportTree	(	le_cfg_IteratorRef_t	iteratorRef,
		const char *LE_NONNULL	filePath,
		const char *LE_NONNULL	nodePath
	)

Take a node given from nodePath and stream it and it's children to the file given by filePath.

This funciton uses the iterator's read transaction, and takes a snapshot of the current state of the tree. The data write happens immediately.

Returns

This function will return one of the following values:

    - LE_OK     - The commit was completed successfuly.
    - LE_FAULT  - An I/O error occured while writing the data.

Parameters

[in]	iteratorRef	Write iterator that is being used for the export.
[in]	filePath	Import the tree data from the this file.
[in]	nodePath	Where in the tree should this export happen? Leave as an empty string to use the iterator's current node.

◆ le_cfgAdmin_DeleteTree()

void le_cfgAdmin_DeleteTree ( const char *LE_NONNULL treeName )

Delete a tree from the system, both from the filesystem and from memory.

Parameters

[in] treeName Name of the tree to delete.

◆ le_cfgAdmin_CreateTreeIterator()

le_cfgAdmin_IteratorRef_t le_cfgAdmin_CreateTreeIterator ( void )

Create a new iterator object for iterating over the list of trees currently managed by the config tree daemon.

◆ le_cfgAdmin_ReleaseTreeIterator()

void le_cfgAdmin_ReleaseTreeIterator ( le_cfgAdmin_IteratorRef_t iteratorRef )

Release the iterator and free it's memory back to the system.

Parameters

[in] iteratorRef Iterator object to release.

◆ le_cfgAdmin_GetTreeName()

le_result_t le_cfgAdmin_GetTreeName	(	le_cfgAdmin_IteratorRef_t	iteratorRef,
		char *	name,
		size_t	nameSize
	)

Read the name of the tree currently pointed at by the iterator.

Returns: LE_OK if there is enough room to copy the name into the supplied buffer. LE_OVERFLOW if not. LE_NOT_FOUND is returned if the list is empty or if the iterator hasn't been moved onto the first item yet.

Parameters

[in]	iteratorRef	Iterator object to read.
[out]	name	Name of the currently referenced tree is passed in this out parameter.
[in]	nameSize

◆ le_cfgAdmin_NextTree()

le_result_t le_cfgAdmin_NextTree ( le_cfgAdmin_IteratorRef_t iteratorRef )

Move onto the next tree in the list. If there are no more trees this function returns false, otherwise true is returned.

Returns: LE_OK if there are more trees to iterate through. LE_NOT_FOUND if not.

Parameters

[in] iteratorRef Iterator to iterate.
