Hi Andrew,

I am trying to figure out the best way to clean up my code (asyn, areaDetector, etc.) to handle the __declspec DLL_EXPORT/IMPORT stuff.

I posted a comment to this thread in ADCore about it just now:

https://github.com/areaDetector/ADCore/issues/455#issuecomment-671933786

It looks like EPICS base 7.0.4 has 2 ways of doing it, for example using LIBCOM_API/LIBCA_API, or the more traditional epicsShareFunc and epicsExportSharedSymbols (e.g. in pvAccess).

I did a "git grep LIBCOM_API" and I cannot actually figure out where LIBCOM_API is defined and how that mechanism works.  Can you explain?

Does the LIBCA_API mechanism rely on anything in base 7, or can it be used with older versions of base?

Thanks,

Mark
