ACE_Read_Guard(3)

This class is similar to class ACE_Guard, though it acquires/releases a read lock automatically (naturally, the ACE_LOCK it is instantiated with must support the appropriate API).

    ACE_Read_Guard (ACE_LOCK &m, int block);
    int acquire_read (void);
    int acquire (void);
    int tryacquire_read (void);
    int tryacquire (void);
    void dump (void) const;
};
