teolarge.c

Send and receive large data blocks between teonet applications

How to execute this test:

1) Start one teonet test application in terminal:

 examples/teolarge teolarge -p 9500

2) Start another test application in other terminal:

 examples/teolarge teorecv -r 9500 -a 127.0.0.1

The first application with name teolarge will send data blocks 2048 bytes length to the teorecv application.
