[Discuss-gnuradio] set_max_output_buffer_size

[Eugene Grayver]

There are a two problems with the set_max_output_buffer_size command:

1. It is not exposed in Python

2. It cannot set the buffer size smaller than the system page size (typically 4k).  This is a big problem for low-rate, low-latency applications.

I cannot provide a pull request, but am attaching a patch that should fix both problems.

The idea behind fixing (2) is simple: allow the system to allocate the full 4k, but keep a local variable with the 'real' buffer size.  Then, simply never report that you have more than 'real' buffer size items free.
