Hi,
Just read the rtl-sdr/include/rtl-sdr.h. It includes all API functions with
helpful notes for each one ;-).
BR,
Nikos

It's not sufficient. The header file does not specify the I/Q
format: the integer encoding and which byte is I and which is Q.
When I needed it, I had to cargo-cult it from bits and pieces
in the sample programs.

I/Q format is 8-bit unsigned, odd bytes are I, even bytes are Q, quite
similar to a stereo wave file.
