Detailed Description

Orchestrates the background mark-and-sweep garbage collector.

The structure encapsulates all state and synchronization needed to run the garbage collector in its own thread. Once started, the GC thread will periodically wake up, scan the heap and any mapped regions for unreachable objects, reclaim them, and then sleep again. The structure holds the timing parameters, the thread handle, and the primitives used to signal the collector to start or stop its work.

Fields:

• gc_thread – Handle to the GC pthread
• main_thread – Handle to the application’s main pthread
• gc_running – Whether the GC thread is active and should run
• gc_exit – Signal for the GC thread to exit
• gc_interval_ms – Interval between GC cycles, in milliseconds
• gc_thread_started – Flag indicating the GC thread has been created
• gc_cond – Condition variable to signal GC thread
• gc_lock – Mutex for synchronizing GC start/stop
