Abstract
A computer system is provided with an operating system that has a streams mechanism for providing streams between user-space processes and drivers. This mechanism permits a user-space process to set up a multiplexer driver for multiplexing and demultiplexing streams. To facilitate the dynamic allocation of new streams to the multiplexer driver, a stream server is associated with the multiplexer driver, the stream server keeping a pool of available streams from which it satisfies any requests for more streams made by the multiplexer driver. The stream server can request a special user-space process to supply new streams to top up the pool.
