NPSavedData - Archive of obsolete content
syntax typedef struct _npsaveddata { int32 len; void* buf; } npsaveddata; fields the data structure has the following fields: len length in bytes of the buffer pointed to by buf; set by the plug-in.
... description the npsaveddata object contains a block of per-instance information that the browser saves after the instance is deleted.
...you can use the plug-in's npp_destroy() function to allocate an npsaveddata object using the npn_memalloc() function, fill in the fields, and return it to the browser as an output parameter.

NPP_Destroy - Archive of obsolete content
syntax #include <npapi.h> nperror npp_destroy(npp instance, npsaveddata **save); parameters the function has the following parameters: instance pointer to the plug-in instance to delete.
...ownership of the buf field of the npsaveddata structure passes from the plug-in to the browser when npp_destroy returns.
... to ensure that the browser does not crash or leak memory when the saved data is discarded, npsaveddata's buf field should be a flat structure (a simple structure with no allocated substructures) allocated with npn_memalloc.
