One of the problems with developing embedded systems is the detection of memory leaks; I've found three tools that are useful for this. These tools are used to detect application program errors, not kernel memory leaks. Two of these tools (mtrace and…

In computer science, a memory leak occurs when a computer program incorrectly manages memory allocations.[1] In object-oriented programming, a memory leak may happen when an object is stored in memory but cannot be accessed by the running code.[2] A…

A real time operating system (RTOS) for embedded controllers having limited memory includes a continuations library, a wide range of macros that hide continuation point management, nested blocking functions, and a communications stack. The RTOS execu…
