Abstract: PROBLEM TO BE SOLVED: To provide latch structure and a managing method for the same with which the simultaneousness of user approach to a critical area is improved by practically providing a latch satisfying the conditions required for the critical area while simplifying the structure and the managing method. SOLUTION: Concerning latch acquiring processing in the latch managing method for supporting the critical area, this processing is provided with at least a first process (S101) for checking whether a user requests the opportunity of latch acquisition issued to a latch managing means in order to enter the critical area or not, second process (S102-S107) for registering the request of user by the latch managing means while occupying mutex by the user, third process (S107) for returning the mutex from the user, and fourth process (S108-S111) for enabling the user to acquire the latch.
