#include <memory> int main() { auto Data = std::unique_ptr<double, void(*)(void*)>{ reinterpret_cast<double*>(malloc(sizeof(double) * 50)), free }; return 0; } So, with std::unique_ptr, you can quickly hack RAII into legacy code. However, as a general guideline, prefer refa...

Ensure that your project does not use std mallocs or relocate FreeRTOS heap for other purposes. The current RA6 FreeRTOS platform port uses FreeRTOS pvPortMalloc(), so it needs a sizable portion of RAM to work. You can change this behavior by overriding the functions in platform/mem- ...

Rather than using malloc() and friends to allocate enough memory for a given object, you ask APR to allocate the memory from a memory pool. When you're finished using the objects you've created in the pool, you destroy the entire pool, effectively de-allocating the memory consumed by all...
