Enumeration Type Documentation

◆ LDServerDataSourceStatus_State

enum LDServerDataSourceStatus_State

Enumeration of possible data source states.

Enumerator
LD_SERVERDATASOURCESTATUS_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_SERVERDATASOURCESTATUS_STATE_VALID, or permanently fails and becomes LD_SERVERDATASOURCESTATUS_STATE_SHUTDOWN.
LD_SERVERDATASOURCESTATUS_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_SERVERDATASOURCESTATUS_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_SERVERDATASOURCESTATUS_STATE_OFF	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

◆ LDServerDataSourceStatus_Free()

LDServerDataSourceStatus_Free ( LDServerDataSourceStatus status )

Frees the data source status.

Parameters

status The data source status to free.

◆ LDServerDataSourceStatus_GetLastError()

LDServerDataSourceStatus_GetLastError ( LDServerDataSourceStatus 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_SERVERDATASOURCESTATUS_STATE_INTERRUPTED, and then subsequent attempts to restart the connection also fail, the state will remain LD_SERVERDATASOURCESTATUS_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_SERVERDATASOURCESTATUS_STATE_VALID.

◆ LDServerDataSourceStatus_GetState()

LDServerDataSourceStatus_GetState ( LDServerDataSourceStatus status )

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

◆ LDServerDataSourceStatus_StateSince()

LDServerDataSourceStatus_StateSince ( LDServerDataSourceStatus 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_SERVERDATASOURCESTATUS_STATE_INITIALIZING, it is the time that the SDK started initializing.
For LD_SERVERDATASOURCESTATUS_STATE_VALID, it is the time that the data source most recently entered a valid state, after previously having been LD_SERVERDATASOURCESTATUS_STATE_INITIALIZING or an invalid state such as LD_SERVERDATASOURCESTATUS_STATE_INTERRUPTED.
For LD_SERVERDATASOURCESTATUS_STATE_INTERRUPTED, it is the time that the data source most recently entered an error state, after previously having been DataSourceState::kValid.
For LD_SERVERDATASOURCESTATUS_STATE_SHUTDOWN, it is the time that the data source encountered an unrecoverable error or that the SDK was explicitly shut down.

◆ LDServerDataSourceStatusListener_Init()

LDServerDataSourceStatusListener_Init ( struct LDServerDataSourceStatusListener * listener )

Initializes a data source status change listener. Must be called before passing the listener to LDServerSDK_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 LDServerSDK_DataSourceStatus_OnStatusChange. NULL will be returned if the StatusChanged member of the listener struct is NULL.

Parameters

listener Listener to initialize.

◆ LDServerSDK_AllFlagsState()

LDServerSDK_AllFlagsState	(	LDServerSDK	sdk,
		LDContext	context,
		enum LDAllFlagsState_Options	options
	)

Evaluates all flags for a context, returning a data structure containing the results and additional flag metadata.

The method's behavior can be controlled by passing a combination of one or more options.

A common use-case for AllFlagsState is to generate data suitable for bootstrapping the client-side JavaScript SDK.

This method will not send analytics events back to LaunchDarkly.

Parameters

sdk	SDK. Must not be NULL.
context	The context against which all flags will be evaluated. Ownership is NOT transferred. Must not be NULL.
options	A combination of one or more options. Pass LD_ALLFLAGSSTATE_DEFAULT for default behavior.

Returns: An AllFlagsState data structure. Must be freed with LDAllFlagsState_Free.

◆ LDServerSDK_BoolVariation()

LDServerSDK_BoolVariation	(	LDServerSDK	sdk,
		LDContext	context,
		char const *	flag_key,
		bool	default_value
	)

Returns the boolean value of a feature flag for a given flag key and context.

bool value = LDServerSDK_BoolVariation(sdk, context, "my-flag", false);

◆ LDServerSDK_New()

LDServerSDK_New ( LDServerConfig config )

Constructs a new server-side LaunchDarkly SDK from a configuration.

LDServerSDK sdk = LDServerSDK_New(config);
 
// Later, when the SDK is no longer in use:
LDServerSDK_Free(sdk);

Parameters

config The configuration. Ownership is transferred. Do not free or access the LDServerConfig in any way after this call, otherwise behavior is undefined. Must not be NULL.

Returns: New SDK instance. Must be freed with LDServerSDK_Free when no longer needed.

◆ LDServerSDK_Start()

LDServerSDK_Start	(	LDServerSDK	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 (LDServerSDK_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.

LDServerSDK_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.
