Re: [Hamlib-developer] Python API

Hi Erik,
Thanks for responding.
My Python 3 app is starting rigctld effectively in the background using 
the subprocessPopen()  mechanism. Then to retrieve parameters from the 
radio, it is running subprocess.Run() which effectively executes "rigctl 
-m 2 f" for example to get the VFO frequency by capturing the response, 
but firing off a windows EXE program every second is pretty awful. I 
assumed I could via the API I assumed was available, open a 
channel/pipe/whatever and effectively do what ever rigctl is doing 
internally.
I've looked at the API references and web pages, but they seem 
convulsively C. I see tantalizing references to python bindings (I'm not 
sure what that means) and in the Debian world I see a python3-hamlib 
library, but of course I'm looking for a Windows solution.
Am I looking for something that doesn't exist Erik?
