I'm updating older code from using the old streaming messaging to the new
and improved message passing and PMTs. However I am getting an error
compiling.
Here is the code snippet:

How long it takes for the Metafile Sink to began recording data?
I have a "No GUI" script that is a simple USRP source, throttle, and
metafile sink. All have a 1M sample rates; the metafile sink has a relative
rate of change of 1, 1M segment size, and have a detached header.
