ringbuffer

Cross platform lock free ringbuffer. Support one reader and one writter,or multi reader and one writter.
NOT SUPPORT MULTI READER AND MULTI WRITTER or ONE READER AND MULTI WRITTER.
If you want to multi writter, you should create multi ringbuffer.

How to use?

Just include atomic_ops.h ring_buffer.h ring_buffer.cpp to your Makefile or other else.
In the source folder,and make will compile a test bin for you.

Sample

How to push

void *p_mem = malloc(RB_SIZE);
RingBuffer rb(RB_SIZE, false, false);
rb_ctx ctx;
rb.push(&ctx, sizeof(ctx), p_mem);

How to pop

rb_ctx ctx;
unsigned int len = 0;
rb.pop(&ctx, &len, p_mem); //p_mem same buffer as push

And an other way to get data

For better performarce, you can get data without copy it to an other buffer.

unsigned int len = 0;
rb_ctx *p_ctx = (rb_ctx*)rb.peek(&len, 0, p_mem);
//processing data
rb.remove(p_mem);

Also more example about how to use, please refer to test_ring_buffer.cpp

Performance

You can run ./test after compile.
On my mbp(Intel(R) Core(TM) i7-4870HQ CPU @ 2.50GHz).
Actually, not like epoll/poll,CPU is wasted on asking.
