executing this code.
The writing participant can access that read_ptr for example to check the=20
available space. But as the docs state (afair), the available sizes for=20
read/write are not strict functions, the only thing that counts is if you h=

space for reading/writing. And that is fulfilled if read_ptr!=3Dwrite_ptr...

Have fun,
