Browser-side plug-in API
This chapter describes methods in the plug-in API that are provided by the browser; these allow call back to the browser to request information, tell the browser to repaint part of the window, and so forth. The names of all of these methods begin with
NPN_ to indicate that they are implemented by the browser and called by the plug-in. 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.
