NAME

ACE_Recursive_Mutex - Implement a C++ wrapper that allows calls to class ACE_Mutex to be nested for a nested acquire() that occurs in the same thread.

SYNOPSIS


#include <ace/Synch.h>


class ACE_Recursive_Mutex
{
  public:
    ACE_Recursive_Mutex (
        int type = USYNC_THREAD,
        const char *name = 0,
        void *arg = 0
        );
    ~ACE_Recursive_Mutex (void);
    int remove (void);
    int acquire (void);
    int tryacquire (void);
    int release (void);
    ACE_Mutex &lock (void);
    thread_t get_thread_id (void);
    int get_nesting_level (void);
    void dump (void) const;
    ACE_ALLOC_HOOK_DECLARE;
  private:
    void set_nesting_level (int d);
    void set_thread_id (thread_t t);
    ACE_Mutex lock_;
    ACE_Mutex nesting_mutex_;
    int nesting_level_;
    thread_t thr_id_;
    inline void operator= (const ACE_Recursive_Mutex &);
    inline ACE_Recursive_Mutex (const ACE_Recursive_Mutex &);
};

DESCRIPTION

Wrappers for various synchronization routines.

Prevent assignment and initialization.

inline void operator= (const ACE_Recursive_Mutex &);
inline ACE_Recursive_Mutex (const ACE_Recursive_Mutex &);
