jvirkki / Libbloom

Introduction

This is libbloom, a simple and small bloom filter implementation in C.

If you are reading this you probably already know about bloom filters and why you might use one. If not, the wikipedia article is a good intro: http://en.wikipedia.org/wiki/Bloom_filter

Building

The Makefile assumes GNU Make, so run 'make' or 'gmake' as appropriate on your system.

By default it builds an optimized 64 bit libbloom. See Makefile comments for other build options.

The shared library will be in ./build/libbloom.so

Sample Usage

#include "bloom.h"

struct bloom bloom; bloom_init(&bloom, 1000000, 0.01); bloom_add(&bloom, buffer, buflen);

if (bloom_check(&bloom, buffer, buflen)) { printf("It may be there!\n"); }

Read bloom.h for more detailed documentation on the public interfaces.
