Alloc

What's this

Small library re-implementation of malloc family of functions.
It makes use of mmap and mremap (thus, for mremap support, requires _GNU_SOURCE).

Internally, It uses a linked list to store memory mappings; header data weights 24B for each memory chunk.

Why?

Because I had free time obviously. And it is a short but nice journey into some linux memory management details.

How to build

It uses cmake, thus:

$ mkdir build
$ cd build
$ cmake ../
$ make

CMake parameters

• -DBUILD_TESTS=true to build tests too (it uses cmocka + valgrind to test for memleaks)
• -DENABLE_PROT=bool to enable/disable mprotect calls on freed memory chunks (disabled by default for performance reasons)

Please do not use this!
