Picotm is a system-level transaction manager. It provides transactional semantics for low-level and operating-system functionality. It’s flexible and extensible to cover exactly your requirements. Error handling and thread isolation are provided by picotm, all you have to implement is the application logic.
Picotm is implemented in plain C and is well-suited for implementing applications and firmware that is secure, reliable and thread-safe; yet easy to develop. This makes picotm well-suited for multi-threaded and fault-tolerant software.
Picotm is Open Source under the terms of the MIT License; viable for use in free and proprietary software.
