Re: genSub subroutine compilation and ioc access

[Matthieu Bec <mbec@gemini.edu>]

Hi Emmanuel,

yes you need to export your gensub's INAM/SNAM - There might be other 
ways to do this but this work. I rarely use the INAM, that can be left 
blank.
say SNAM=xxx
in C source, do: epicsExportRegistrar(xxx)
in dbd include, do: registrar("xxx")

the application developper's guide has more details, I remember 
convenience macros(?) to epicsExportRegistrar
