## NAME

ACE_Local_WLock - Class that acquires, renews, and releases a writer lock that is local to the process.

## SYNOPSIS

    #include <ace/Local_Tokens.h>

    class ACE_Local_WLock : public ACE_Token_Proxy
    {
      public:
        ACE_Local_WLock (
            const ASYS_TCHAR *token_name = 0,
            int ignore_deadlock = 0,
            int debug = 0
            );
        ~ACE_Local_WLock (void);
        void dump (void) const;
        virtual int type (void) const;
        virtual ACE_Token_Proxy *clone (void) const;
      protected:
        ACE_Tokens *create_token (const ASYS_TCHAR *name);
    };

## DESCRIPTION

This file contains definitions for the following classes:

public: 7. ACE_Token_Proxy 8. ACE_Null_Token : public ACE_Token_Proxy 9. ACE_Local_Mutex : public ACE_Token_Proxy *. ACE_Local_RLock : public ACE_Local_Mutex &. ACE_Local_WLock : public ACE_Local_Mutex private: 1. ACE_TOKEN_CONST 3. ACE_TPQ_Entry b. ACE_TSS_TPQ_Entry c. ACE_TPQ_Iterator 4. ACE_Token_Proxy_Queue 5. ACE_Tokens 6. ACE_Mutex_Token : public ACE_Tokens 12. ACE_RW_Token : public ACE_Tokens a. ACE_Token_Name

## Initialization and termination.

    ACE_Local_WLock (
        const ASYS_TCHAR *token_name = 0,
        int ignore_deadlock = 0,
        int debug = 0
        );

`token_name` uniquely id's the token. `ignore_deadlock` will allow deadlock to occur (useful for testing). `debug` prints a bunch of messages.

    ~ACE_Local_WLock (void);

Destructor

    void dump (void) const;

Dump the state of the class.

    virtual int type (void) const;

Returns ACE_RW_Token::WLOCK.

    virtual ACE_Token_Proxy *clone (void) const;

Return deep copy.
