Documentation requirements

[hjunkes]

is there already a template how to document the header files with doxygen?

Some of the yajl headers have doxygen markup in them (from the original author), although we might want to suggest a different set of conventions (both @ralphlange and @mdavidsaver seem to prefer @keyword instead of \keyword which is fine by me). I had a marked-up version of epicsExport.h which I had worked on some time back that I just created PR #2 with that which could serve as some kind of template, although that particular file only has macro definitions in it so it isn't a comprehensive example.

I have been adding comments to @hjunkes 's pull request for postfix.h about the defgroup directive.
I think it is useful, because it adds entries under the Modules heading in the doxygen generated pages.
I am adding a group in the doxygen comments in resourceLib.h
