[webkit-help] [webkit-dev] NPAPI plugin crashes while calling npnfuncs->invoke in GtkLauncher

[souvik.datta at wipro.com]

Yes I am aware of that. That is why I am using npnfuncs->pluginthreadasynccall(). Kindly note  that this same plugin working fine on Firefox.
Can you please tell me whether one should do anything specific for developing a NPAPI plugin for Webkit? 

My understanding is that the plugin that I developed for Firefox should also just work for Webkit (GtkLauncher ). For Webkit,  I have only replaced the header files that I had for Firefox with the ones available in path: WebCore/plugins/

Just a question, are you using threads in your NPAPI plugin? Because the
NPAPI is not thread-safe, so you cannot call back the browser in a
different thread than the one used by the browser to communicate with
your plugin.
