We are not quite sure what you want here, can you please expand on this

We have mimicked the mechanism used today to setup a new VLC plugin to
get the options. We now support both a string of options or an array of
strings (exactly the same as the options for a new plugin). We have
deliberately not called the LibvlcPlaylistNPObject::parseOptions method
for the following two reasons:
- it is apparently bound to evolve quite a bit according to the number
of FIXMEs and we are not sure our code will be compatible with such
evolutions and/or that our code won't prevent such evolutions
- this method is not naturally accessed from within the plugin and all
the circonvolutions don't seem appropriate and logical

We have changed the map of strings for a map of NPUTF8*. We have also
hidden said map as well as another global (the eventToCatch bitmask) in
the VlcPLugin object.

The function now returns void on success, and throws an exception with
the message on error.
Moreover, we noticed on *our* development platform that compilation
fails because the HAS_NPFUNCTIONS_H variable is not #defined for us. We
had to manually define it, otherwise compiler uses npupp.h instead of
npfunctions.h, which doesn't define the API functions we need for our patch.
Possible solutions are:
- use a better development platform than ours ;)
- define HAS_NPFUNCTIONS_H manually at compilation time if npfunctions.h
- define HAS_NPFUNCTIONS_H in appropriate header file (npapi.h or
npunix.h, not sure where this should be)
Awaiting on your comments, thanks for all the help,
