[olsr-dev] Re: Socket parser and HNA routes' update [QUESTIONS]

[Gianni Costanzi]

Can someone at least tell me where the implementation of
olsr_plugin_io has been moved to? plugin.c is disappeared from 0.5.0
sources (in 0.4.9 there are plugin.c and olsr_plugin_io.h where all
the constants that are used to specify which function we want to
replace are defined)..
I noticed that in the changelog here [1], about 0.4.10, it is said
"Plugin interface changes. Olsrd now exports all symbols mening that
plugins can access all olsrd functions easily."

Does this "only" mean that plugins can access all the functions of
olsrd or does it mean also that they can replace whatever function
they want? If the last one, how?
