Enumeration Type Documentation

◆ LDDataSourceStatus_State

enum LDDataSourceStatus_State

Enumeration of possible data source states.

Enumerator
LD_DATASOURCESTATUS_STATE_INITIALIZING	The initial state of the data source when the SDK is being initialized. If it encounters an error that requires it to retry initialization, the state will remain at kInitializing until it either succeeds and becomes LD_DATASOURCESTATUS_STATE_VALID, or permanently fails and becomes LD_DATASOURCESTATUS_STATE_SHUTDOWN.
LD_DATASOURCESTATUS_STATE_VALID	Indicates that the data source is currently operational and has not had any problems since the last time it received data. In streaming mode, this means that there is currently an open stream connection and that at least one initial message has been received on the stream. In polling mode, it means that the last poll request succeeded.
LD_DATASOURCESTATUS_STATE_INTERRUPTED	Indicates that the data source encountered an error that it will attempt to recover from. In streaming mode, this means that the stream connection failed, or had to be dropped due to some other error, and will be retried after a backoff delay. In polling mode, it means that the last poll request failed, and a new poll request will be made after the configured polling interval.
LD_DATASOURCESTATUS_STATE_OFFLINE	Indicates that the application has told the SDK to stay offline.
LD_DATASOURCESTATUS_STATE_SHUTDOWN	Indicates that the data source has been permanently shut down. This could be because it encountered an unrecoverable error (for instance, the LaunchDarkly service rejected the SDK key; an invalid SDK key will never become valid), or because the SDK client was explicitly shut down.

Function Documentation

◆ LDClientSDK_AllFlags()

LDClientSDK_AllFlags ( LDClientSDK sdk )

Returns a map from feature flag keys to feature flag values for the current context.

In the example, all flags of type boolean are printed.

LDValue_ObjectIter it;
for (it = LDValue_ObjectIter_New(all_flags);
!LDValue_ObjectIter_End(it); LDValue_ObjectIter_Next(it)) { char
const* flag_key = LDValue_ObjectIter_Key(it); LDValue flag_val_ref =
LDValue_ObjectIter_Value(it);
 
  if (LDValue_Type(flag_val_ref) == LDValueType_Bool) {
      printf("%s: %d\n", flag_key, LDValue_GetBool(flag_val_ref));

◆ LDClientSDK_FlagNotifier_OnFlagChange()

LDClientSDK_FlagNotifier_OnFlagChange	(	LDClientSDK	sdk,
		char const *	flag_key,
		struct LDFlagListener	listener
	)

Listen for changes for the specific flag.

If the FlagChanged member of the listener struct is not set (NULL), then the function will not register a listener. In that case the return value will be NULL.

Parameters

sdk	SDK. Must not be NULL.
flag_key	The unique key for the feature flag. Must not be NULL.
listener	The listener, whose FlagChanged callback will be invoked, when the flag changes. Must not be NULL.

Returns: A LDListenerConnection. The connection can be freed using LDListenerConnection_Free and the listener can be disconnected using LDListenerConnection_Disconnect. NULL will be returned if the FlagChanged member of the listener struct is NULL.

◆ LDClientSDK_Flush()

LDClientSDK_Flush	(	LDClientSDK	sdk,
		unsigned int	reserved
	)

Requests delivery of all pending analytic events (if any).

You MUST pass LD_NONBLOCKING as the second parameter.

Parameters

sdk	SDK. Must not be NULL.
milliseconds	Must pass `LD_NONBLOCKING`.

◆ LDClientSDK_Free()

LDClientSDK_Free ( LDClientSDK sdk )

Frees the SDK's resources, shutting down any connections. May block.

Parameters

sdk SDK.

◆ LDClientSDK_Identify()

LDClientSDK_Identify	(	LDClientSDK	sdk,
		LDContext	context,
		unsigned int	milliseconds,
		bool *	out_succeeded
	)

Changes the current evaluation context, requests flags for that context from LaunchDarkly if online, and generates an analytics event to tell LaunchDarkly about the context.

Only one Identify call can be in progress at once; calling it concurrently invokes undefined behavior.

The method may be blocking or asynchronous depending on the arguments.

To block, pass a positive milliseconds value and an optional pointer to a boolean. The return value will be true if the SDK was able to attempt the operation within the specified timeframe, or false if the operation couldn't complete in time. The value of out_succeeded will be true if the SDK successfully changed evaluation contexts.

Example:

bool identified_successfully;
if (LDClientSDK_Identify(client, context, 5000, &identified_successfully)) {
    // The client was able to re-initialize in less than 5 seconds.
    if (identified_successfully) {
        // Evaluations will use data for the new context.
    else {
        // Evaluations will continue using existing data.
    }
} else {
   // The client is still identifying.
}

To start asynchronously, pass LD_NONBLOCKING. In this case, the return value will be false and you may pass NULL to out_succeeded.

// Returns immediately.

LDClientSDK_Identify(client, context, LD_NONBLOCKING, NULL);

Parameters

sdk	SDK. Must not be NULL.
context	The new evaluation context.
milliseconds	Milliseconds to wait for identify to complete, or `LD_NONBLOCKING` to return immediately.
out_succeeded	Pointer to bool representing successful identification. Only modified if a positive milliseconds value is passed; may be NULL.

Returns: True if the client started within the specified timeframe.

◆ LDClientSDK_Initialized()

LDClientSDK_Initialized ( LDClientSDK sdk )

Returns a boolean value indicating LaunchDarkly connection and flag state within the client.

When you first start the client, once Start has completed, Initialized should return true if and only if either 1. it connected to LaunchDarkly and successfully retrieved flags, or 2. it started in offline mode so there's no need to connect to LaunchDarkly.

If the client timed out trying to connect to LD, then Initialized returns false (even if we do have cached flags). If the client connected and got a 401 error, Initialized is will return false. This serves the purpose of letting the app know that there was a problem of some kind.

Parameters

sdk	SDK. Must not be NULL.

Returns: True if initialized.

◆ LDClientSDK_IntVariation()

LDClientSDK_IntVariation	(	LDClientSDK	sdk,

Returns: The variation for the current context, or default_value if the flag is disabled in the LaunchDarkly control panel.

◆ LDClientSDK_JsonVariation()

LDClientSDK_JsonVariation	(	LDClientSDK	sdk,
		char const *	flag_key,
		LDValue	default_value
	)

Returns the JSON value of a feature flag for a given flag key.

◆ LDClientSDK_New()

LDClientSDK_New	(	LDClientConfig	config,
		LDContext	context
	)

Constructs a new client-side LaunchDarkly SDK from a configuration and context.

Parameters

config	The configuration. Ownership is transferred. Do not free or access the LDClientConfig in any way after this call; behavior is undefined. Must not be NULL.
context	The initial context. Ownership is transferred. Do not free or access the LDContext in any way after this call; behavior is undefined. Must not be NULL.

◆ LDClientSDK_Start()

LDClientSDK_Start	(	LDClientSDK	sdk,
		unsigned int	milliseconds,
		bool *	out_succeeded
	)

Starts the SDK, initiating a connection to LaunchDarkly if not offline.

Only one Start call can be in progress at once; calling it concurrently invokes undefined behavior.

The method may be blocking or asynchronous depending on the arguments.

To block, pass a positive milliseconds value and an optional pointer to a boolean. The return value will be true if the SDK started within the specified timeframe, or false if the operation couldn't complete in time. The value of out_succeeded will be true if the SDK successfully initialized.

Example:

bool initialized_successfully;
if (LDClientSDK_Start(client, 5000, &initialized_successfully)) {
    // The client was able to initialize in less than 5 seconds.
    if (initialized_successfully) {
        // Initialization succeeded.
    else {
        // Initialization failed.
    }
} else {
   // The client is still initializing.
}

To start asynchronously, pass LD_NONBLOCKING. In this case, the return value will be false and you may pass NULL to out_succeeded.

// Returns immediately.

LDClientSDK_Start(client, LD_NONBLOCKING, NULL);

Parameters

sdk	SDK. Must not be NULL.
milliseconds	Milliseconds to wait for initialization or `LD_NONBLOCKING` to return immediately.
out_succeeded	Pointer to bool representing successful initialization. Only modified if a positive milliseconds value is passed; may be NULL.

Returns: True if the client started within the specified timeframe.

	)

Tracks that the current context performed an event for the given event name.

Parameters

sdk	SDK. Must not be NULL.
event_name	Name of the event. Must not be NULL.

◆ LDClientSDK_TrackMetric()

LDClientSDK_TrackMetric	(	LDClientSDK	sdk,
		char const *	event_name,
		double	metric_value,
		LDValue	data
	)

Parameters

sdk	SDK. Must not be NULL.
event_name	The name of the event. Must not be NULL.
metric_value	this value is used by the LaunchDarkly experimentation feature in numeric custom metrics, and will also be returned as part of the custom event for Data Export.

◆ LDClientSDK_Version()

LDClientSDK_Version ( void )

Returns the version of the SDK.

Returns: String representation of the SDK version.

◆ LDDataSourceStatus_Free()

LDDataSourceStatus_Free ( LDDataSourceStatus status )

Frees the data source status.

Parameters

status The data source status to free.

◆ LDDataSourceStatus_GetLastError()

LDDataSourceStatus_GetLastError ( LDDataSourceStatus status )

Information about the last error that the data source encountered, if any. If there has not been an error, then NULL will be returned.

If a non-NULL value is returned, then it should be freed using LDDataSourceStatus_ErrorInfo_Free.

This property should be updated whenever the data source encounters a problem, even if it does not cause the state to change. For instance, if a stream connection fails and the state changes to LD_DATASOURCESTATUS_STATE_INTERRUPTED, and then subsequent attempts to restart the connection also fail, the state will remain LD_DATASOURCESTATUS_STATE_INTERRUPTED but the error information will be updated each time– and the last error will still be reported in this property even if the state later becomes LD_DATASOURCESTATUS_STATE_VALID.

◆ LDDataSourceStatus_GetState()

LDDataSourceStatus_GetState ( LDDataSourceStatus status )

Get an enumerated value representing the overall current state of the data source.

◆ LDDataSourceStatus_State_Name()

LDDataSourceStatus_State_Name	(	enum LDDataSourceStatus_State	state,
		char const *	default_if_unknown
	)

Parameters

state	The state to convert to a string.
default_if_unknown	The default string to return if the state is not recognized.

Returns: Returns the name of the given LDDataSourceStatus_State.

◆ LDDataSourceStatus_StateSince()

LDDataSourceStatus_StateSince ( LDDataSourceStatus status )

The date/time that the value of State most recently changed, in seconds since epoch.

The meaning of this depends on the current state:

For LD_DATASOURCESTATUS_STATE_INITIALIZING, it is the time that the SDK started initializing.
For LD_DATASOURCESTATUS_STATE_VALID, it is the time that the data source most recently entered a valid state, after previously having been LD_DATASOURCESTATUS_STATE_INITIALIZING or an invalid state such as LD_DATASOURCESTATUS_STATE_INTERRUPTED.
For LD_DATASOURCESTATUS_STATE_INTERRUPTED, it is the time that the data source most recently entered an error state, after previously having been DataSourceState::kValid.
For LD_DATASOURCESTATUS_STATE_SHUTDOWN, it is the time that the data source encountered an unrecoverable error or that the SDK was explicitly shut down.

◆ LDDataSourceStatusListener_Init()

LDDataSourceStatusListener_Init ( struct LDDataSourceStatusListener * listener )

Initializes a data source status change listener. Must be called before passing the listener to LDClientSDK_DataSourceStatus_OnStatusChange.

If the StatusChanged member of the listener struct is not set (NULL), then the function will not register a listener. In that case the return value will be NULL.

Create the struct, initialize the struct, set the StatusChanged handler and optionally UserData, and then pass the struct to LDClientSDK_DataSourceStatus_OnStatusChange. NULL will be returned if the StatusChanged member of the listener struct is NULL.

Parameters

listener Listener to initialize.
