In multithreaded C/C++ programming, protecting shared resources is key, and critical sections are a lightweight solution for Windows developers. A critical section is a synchronization object that ensures only one thread accesses a code block at a time—perfect for avoiding race conditions. Using CRITICAL_SECTION with EnterCriticalSection() and LeaveCriticalSection(), you can lock and unlock efficiently within the same process. It’s simpler and faster than a mutex for single-process apps! Want to see how it works in practice?
