Problem Description
Resource Acquisition Is Initialization (RAII) is a fundamental idiom in C++ systems programming, ensuring deterministic resource management essential for high-frequency trading environments where latency and stability are paramount. By binding the life cycle of a resource, such as a POSIX file descriptor, to the lifetime of an object, developers prevent resource leaks and ensure proper cleanup. This pattern is critical for maintaining robust infrastructure in quantitative finance applications.
