Provides global deinitialization for a plug-in.
#include <npapi.h> void NP_Shutdown(void);
#include <npapi.h> void WINAPI NP_Shutdown(void);
The browser calls this function once after the last instance of your plug-in is destroyed, before unloading the plug-in library itself. Use
NP_Shutdown to delete any data allocated in
NP_Initialize to be shared by all instances of a plug-in.
If you have defined a Java class for your plug-in, be sure to release it at this time so that Java can unload it and free up memory.
NOTE: If enough memory is available, the browser can keep the plug-in library loaded if it expects to create more instances in the near future. The browser calls
NP_Shutdown only when the library is finally unloaded.
