Number of elements in pipe

[clivehaworth]

Hi,
I'm trying to use pipe.c as the underlying mechanism for a Java InputStream in a JNI project.

All good - but I need a way to get the number of elements in the pipe at a specified time.

Is this possible?

You can try add function like this:

size_t pipe_bytes(pipe_generic_t * p)
{
    return bytes_in_use(make_snapshot(p));   
}

and then get number of elements:

elements = pipe_bytes(p) / pipe_elem_size(p);
