Fixed Buffer Memory Allocator

My implementation of Fixed Buffer Memory Allocator in C.

How it works?

This memory allocator designed to minimize the calls to malloc and free (in general, system calls) because they tend to be slow. The allocator allocates a fixed size buffer (4096 Bytes by default) and uses that to store data.

Take a look at test/test.c file to see how to use this memory allocator.

Public API

Constants

There are 3 constants in src/balloc.h file that you can modify.

BALLOC_DEBUG

Set this constant to 1 to enable logging.

BALLOC_PTR_MD

Set this constant to 1 to store pointers metadata. This will waste a size of size_t type for each pointer on the buffer. But, to do some memory operations safely (since all data lives in a buffer) it's important to know each pointer's size.

DEFAULT_BUFF_SIZE

Default buffer size. (4096 Bytes)

Functions

balloc_new

Create and construct a new fixed buffer allocator with type BuffAlloc.

Other funcitons

Take a look at src/balloc.h in Public API section for all functions that are available to you. You can also read test/test.c file to see how to use public API and some functions that balloc provides.
