Dynamic Memory Allocator: Multi-Pool

This project:

Executed a multi-pool allocator in programming language C and provided memory allocation functions such as malloc (), calloc(), and realloc(). Performed free () function to free memory regions allocated by any of the above allocation functions

The src/ directory contains the source code for your allocator, as well as some helper code. As given, it is a barely-working allocator that uses sbrk() to directly allocate memory from the operating system for every request. It does not implement realloc(), so many applications will not run.

You should implement your entire allocator in src/mm.c. The bulk allocator is also in src/bulk.c, but you should not modify the bulk allocator for your implementation; the Autograder will test your implementation using the given bulk allocator.

The tests/ directory contains two simple tests; one of them tests the bulk allocator (which, as stated above, you should not modify; this test is just a sanity check to make sure the bulk allocator is working, and to give you an example of a test), and the other tests to make sure that sbrk() is not called between two requests for the same size allocation. Note that this second test will pass with the given allocator, but that the given allocator is NOT a correct allocator; however, if your allocator has bugs, it may well fail this test! These two tests should help you see how to design and run your own tests.

The default make target (built by invoking make) builds the shared object (library) file libcsemalloc.so. This object contains your allocator and can be used to run your standard Unix utilities using your allocator. Instructions for how to do this are in the Makefile.
