Detailed Description

Statically initialized mutex wrapper for globals touched during startup. The embedded mutex carries the platform lock and initialized records whether runtime setup has completed; callers use normal mutex operations after initialization.

Reader-writer lock wrapper for global state that needs safe static initialization. lock is the platform lock and initialized makes one-time setup visible; the global owner retains it until process shutdown.

Wrapper for a condition variable that must be usable before normal runtime initialization. cond contains the platform primitive and initialized prevents duplicate setup; global owners keep it for the process lifetime rather than freeing it like a heap condition variable.

Static reader-writer lock structure for global rwlocks requiring static initialization

Provides lazy initialization for reader-writer locks that need to work before main(). Uses the same lazy initialization pattern as static_mutex_t for cross-platform compatibility.

Note

The initialized flag is checked atomically before first use to ensure the rwlock is initialized exactly once.
