I wanted to learn more about the under the hood of C.
What it does
It allows the user to allocate blocks of memory, much like malloc.
How I built it
I used sbrk and brk to get pages of memory from the OS. I then had arrays to keep track of what blocks were in use and which ones weren't.
Challenges I ran into
Keeping track of the block layout and "freeing" them properly, as well as knowing minimizing fragmentation.
What I learned
How sbrk/brk work, (a little bit of) how malloc works under the hood.
What's next for Allocator
Write an implementation using mmap
