But the kernel won't tell you the areas of free memory without other system calls very much like malloc, which is, as I understand it, not what nate wants. The hooks are only ... How is malloc() implemented? I want to create my own version of it, but that would be much easier if I had its source code. I am using MinGW.

Here you can download the third version of ptmalloc (C source code), a fast, memory-efficient implementation of malloc for Unix systems. ptmalloc is based on code by Doug Lea and was extended for use with multiple threads (especially on SMP systems).

One of the most common questions that get asked during interviews for C++ programmers is to explain the differences between using malloc and using new. It's also a fairly common question in some of newsgroups and C++ forums. ... Similarly, the above code snippet is just as bad and probably worse by a good deal.
