Ask your administrator if you think this is wrong. ====== Lock Semaphores ====== In order to remain compatible with the variety of networks supported in OpenInsight, the system uses a standard protocol for the establishment of locks. This is based on lock semaphores. When a BASIC+ [[lock|LOCK statement]] is executed, the system uses the file handle and record key information (if locking a record) to create a lock semaphore. In order to accommodate all potential network locking schemes, the semaphore is simplified by hashing the file and record information into a reduced eight-byte format. guides/programming/programmers_reference_manual/lock_semaphores.txt Last modified: 2024/06/19 20:20by 127.0.0.1
