Detailed Description

Hook structure containing callback function pointers.

USAGE:

1. Allocate an LDServerSDKHook struct (stack or heap)
2. Call LDServerSDKHook_Init() to initialize it
3. Set the Name field (required, UTF-8 encoded, null-terminated)
4. Set any callback function pointers you need (NULL if not used)
5. Set UserData to application-specific context (NULL if not needed)
6. Register with LDServerConfigBuilder_Hooks()

EXAMPLE:

struct LDServerSDKHook my_hook;
LDServerSDKHook_Init(&my_hook);
my_hook.Name = "MyTracingHook";
my_hook.BeforeEvaluation = my_before_callback;
my_hook.AfterEvaluation = my_after_callback;
my_hook.UserData = my_context;
LDServerConfigBuilder_Hooks(builder, my_hook);

LIFETIME:

• The LDServerSDKHook struct itself can be stack-allocated or freed after registration (the SDK copies it)
• The Name string must remain valid until LDServerConfigBuilder_Build()
• UserData must remain valid for the entire SDK client lifetime

Optional callback invoked before evaluations. Set to NULL if not needed.

Name

char const* LDServerSDKHook::Name

Name of the hook. Required. Must be a null-terminated UTF-8 string. Must remain valid until LDServerConfigBuilder_Build() is called.
