Multithreading in GR blocks

[Moses Browne Mwakyanjala]

Hello everyone,

I have created a TCP/IP block by adapting the ZMQ message pub block. Both blocks make use of boost multithreading. The TCP/IP block is used by a standalone C++ program. To run the gnuradio topblock, the C++ program calls tb->start() function. To stop the topblock, the functions tb->stop() and tb->wait() are called.However, the program "hangs" when tb->stop() is called. This suggests there is something wrong with the way I use boost multithreading. 

All help is appreciated.

Regards,

Moses.
