## NAME

ACE_TSS_Guard - This data structure is meant to be used within a method or function... It performs automatic aquisition and release of a synchronization object. Moreover, it ensures that the lock is released even if a thread exits via "thr_exit()"!

## SYNOPSIS

    #include <ace/Synch_T.h>

    template<class ACE_LOCK>
    class ACE_TSS_Guard
    {
      public:
        ACE_TSS_Guard (ACE_LOCK &lock, int block = 1);
        ~ACE_TSS_Guard (void);
        int acquire (void);
        int tryacquire (void);
        int release (void);
        int remove (void);
        void dump (void) const;
      protected:
        ACE_TSS_Guard (void);
        void init_key (void);
        static void cleanup (void *ptr);
        ACE_thread_key_t key_;
      private:
        inline ACE_UNIMPLEMENTED_FUNC (
            void operator= (const ACE_TSS_Guard<ACE_LOCK> &)
            );
    };

## Initialization and termination methods.

    ACE_TSS_Guard (ACE_LOCK &lock, int block = 1);

Implicitly and automatically acquire the thread-specific lock.

    ~ACE_TSS_Guard (void);

Implicitly release the thread-specific lock.

## Lock accessors.

    int acquire (void);

Explicitly acquire the thread-specific lock.

    int tryacquire (void);

Conditionally acquire the thread-specific lock (i.e., won't block).

    int release (void);

Explicitly release the thread-specific lock.

## Utility methods.

    int remove (void);

Explicitly release the thread-specific lock.

    void dump (void) const;

Dump the state of an object.

ACE_ALLOC_HOOK_DECLARE; Declare the dynamic allocation hooks.

## Prevent assignment and initialization.

    inline ACE_UNIMPLEMENTED_FUNC (
        void operator= (const ACE_TSS_Guard<ACE_LOCK> &)
        );
