Enumeration Type Documentation

◆ keyflag_t

enum keyflag_t

Key Flags.

Store a synchronizer state so that the Elektra knows if something has changed or not.

Enumerator
KEY_FLAG_SYNC	Key need sync. If name, value or metadata are changed this flag will be set, so that the backend will sync the key to database.
KEY_FLAG_RO_NAME	Read only flag for name. Key name is read only and not allowed to be changed. All attempts to change the name will lead to an error. Needed for metakeys and keys that are in a data structure that depends on name ordering.
KEY_FLAG_RO_VALUE	Read only flag for value. Key value is read only and not allowed to be changed. All attempts to change the value will lead to an error. Needed for metakeys
KEY_FLAG_RO_META	Read only flag for meta. Key meta is read only and not allowed to be changed. All attempts to change the value will lead to an error. Needed for metakeys.

◆ ksflag_t

enum ksflag_t

Function Documentation

◆ backendOpen()

Backend* backendOpen	(	KeySet *	elektraConfig,
		KeySet *	modules,
		Key *	errorKey
	)

Builds a backend out of the configuration supplied from:

system/elektra/mountpoints/<name>

The root key must be like the above example. You do not need to rewind the keyset. But every key must be below the root key.

The internal consistency will be checked in this function. If necessary parts are missing, like no plugins, they cant be loaded or similar 0 will be returned.

ksCut() is perfectly suitable for cutting out the configuration like needed.

Note: The given KeySet will be deleted within the function, don't use it afterwards.

Parameters

elektraConfig	the configuration to work with. It is used to build up this backend.
modules	used to load new modules or get references to existing one
errorKey	the key where an error and warnings are added

Returns: a pointer to a freshly allocated backend this could be the requested backend or a so called "missing backend".

Return values

0	if out of memory

◆ backendOpenDefault()

Backend* backendOpenDefault	(	KeySet *	modules,
		const char *	file,
		Key *	errorKey
	)

Opens a default backend using the plugin named KDB_RESOLVER and KDB_STORAGE.

Parameters

modules	the modules to work with
errorKey	the key to issue warnings and errors to

Returns: the fresh allocated default backend or 0 if it failed

◆ backendOpenModules()

Backend* backendOpenModules	(	KeySet *	modules,
		Key *	errorKey
	)

Returns: a backend which gives plugin configuration of the module which is currently point to.

Parameters

modules	the modules to work with
errorKey	the key to issue warnings and errors to

◆ backendOpenVersion()

Backend* backendOpenVersion ( Key * errorKey )

Opens the internal version backend.

Parameters

errorKey the key to issue warnings and errors to

Returns: the fresh allocated default backend or 0 if it failed

◆ backendUpdateSize()

int backendUpdateSize	(	Backend *	backend,
		Key *	parent,
		int	size
	)

Update internal size in backend.

Parameters

backend	the backend to update
parent	for parent
size	to update (-1 default, 0 empty, >0 otherwise)

Precondition: parent must be serializable namespace

Return values

-1	if invalid parent (assert)
0	on success

◆ elektraKeyLock()

int elektraKeyLock	(	Key *	key,
		enum elektraLockOptions	what
	)

Permanently locks a part of the key.

This can be:

KEY_FLAG_LOCK_NAME to lock the name
KEY_FLAG_LOCK_VALUE to lock the value
KEY_FLAG_LOCK_META to lock the metadata

To unlock the key, duplicate it.

It is also possible to lock when the key is created with keyNew().

Some data structures need to lock the key (most likely its name), so that the ordering does not get confused.

Parameters

key	which name should be locked

See also: keyNew(), keyDup(), ksAppendKey()

Return values

>0	the bits that were successfully locked
0	if everything was locked before
-1	if it could not be locked (nullpointer)

◆ elektraKsPopAtCursor()

Key* elektraKsPopAtCursor	(	KeySet *	ks,
		cursor_t	pos
	)

Pop key at given cursor position.

Parameters

ks	the keyset to pop key from
c	where to pop

The internal cursor will be rewinded using ksRewind(). You can use ksGetCursor() and ksSetCursor() jump back to the previous position. e.g. to pop at current position within ksNext() loop:

cursor_t c = ksGetCursor(ks);
keyDel (ksPopAtCursor(ks, c));
ksSetCursor(ks, c);
ksPrev(ks); // to have correct key after next ksNext()

Warning: do not use, will be superseded by external iterator API

Returns: the popped key

Return values

0	if ks is 0

◆ elektraKsPrev()

Key* elektraKsPrev ( KeySet * ks )

Returns the previous Key in a KeySet.

KeySets have an internal cursor that can be reset with ksRewind(). Every time ksPrev() is called the cursor is decremented and the new current Key is returned.

You'll get a NULL pointer if the key before begin of the KeySet was reached.

Don't delete the key, use ksPop() if you want to delete it.

Returns: the new current Key

See also: ksRewind(), ksCurrent()

Return values

-1	on null pointers
0	if nothing was done
