NPAPI plug-in side API

This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Avoid using it and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

This chapter describes methods in the plug-in API that are available from the plug-in object; these allow plug-ins to interact with the browser. The names of all of these methods begin with NPP_ to indicate that they are implemented by the plug-in and called by the browser. For an overview of how these two sides of the plug-in API interact, see the How Plug-ins Work and Overview of Plug-in Structure sections in the introduction.
