npstream; fields the data structure has the following fields: plug-in-private value that the plug-in can use to store a pointer to private data associated with the instance; not modified by the browser.
... description the browser allocates and initializes the
npstream object and passes it to the plug-in in as a parameter to npp_newstream or npn_newstream.
...streams produced by the browser: the browser creates the
npstream object and passes it to the plug-in initially as a parameter to npp_newstream.

Streams - Plugins
the browser can create a stream for several different types of data: for the file specified in the data attribute of the object element or the src attribute of the embed element for a data file for a full-page instance the npp_newstream method has the following syntax: nperror npp_newstream(npp instance, npmimetype type,
npstream *stream, npbool seekable, uint16* stype); the instance parameter refers to the plug-in instance receiving the stream; the type parameter represents the stream's mime type.
...once the plug-in returns from this method, the browser deletes the
npstream object.
... nperror npp_destroystream(npp instance,
npstream *stream, nperror reason); the instance parameter is the current plug-in instance; the stream parameter specifies the stream to be deleted.

Getting the page URL in NPAPI plugin - Archive of obsolete content
tradeoffs: uses npapi only works in most browsers does not work in mozillas older than firefox 1.0 via npp_newstream from braden mcdaniel: if you want the uri of the resource for which the plug-in is invoked, the most npapi-friendly way to do that is to get it from the
npstream that is passed to npp_newstream.
