Have a look at the source code of your libc.

The malloc implementation inside glibc is not very easy to
understand, because it is "production" code, optimized for speed,
multi-threaded access, etc.

A much simpler implementation can be found in K&R (2nd edition,
p.185) -- Chapter 8.7 Example -- A Storage Allocator.
