Re: [Discuss-gnuradio] format of data in datafile produced by file_sink_c

[Josh Blum]

file_sink_c prodces complex floating point. Every 8 bytes is a complex 
float, where the first 4 bytes is a float representing I, and the second 
4 bytes a float representing Q.

if you were using numpy, it could be read with: numpy.fromfile(file, 
numpy.complex64)
