Osmocom C files syntax understanding

[Tomcsányi, Domonkos]

Hello Mario,

I think you have not checked everywhere :). Even a quick google search
(if you don't want use grep) for gsm_bts_trx returns the file:
bts_trx.h
https://github.com/osmocom/osmo-bts/blob/master/include/osmo-bts/bts_trx.h

Cheers,
Domi
