A Custom Malloc implementation using a best fit allocator with a in memory double linked list implementation, that stores status (free, allocated) information.
This conforms mostly to POSIX malloc, realloc, free specification, but for more details, see the function documentation.
It is fully thread safe (with a mutex by default), you can turn it off, if you like the minimal additional speed and can assure, that it's not used in MT context.
It also implements a thread_local variant, sop that each thread has it's own mmmap'ed storage pool.
The my_malloc, my_realloc, my_free functions all define valgrind compatible blocks, so if you have valgrind headers installed, it uses those and you can run the programm with valgrind, to check for memory leeks.
You need certain things for this to work:
- meson - install from here
- A C2x std compatible compiler (e.g. GCC)
- A C++ compatible compiler (onyl for tests with gtest)
meson setup build
meson compile -C build
meson test -C build --verbose # for tests
./build/src/task2/tests_with_double_pointers --all
