[linux-dvb] How to runtime-detect S2API kernel?

Hi list,


Is there an official safe way to detect S2API capable DVB drivers at 
runtime, so that a program compiled against S2API headers can check for 
S2API drivers and switch to old API otherwise?

Does it work to call FE_HAS_EXTENDED_CAPS? Do all old drivers return 
this flag under the new API, or only S2API-aware drivers?

Or is it better to call FE_SET_PROPERTY with num=0 commands? Does this 
always return success under S2API?


Cheers,

Udo
