The WindNet STREAMS for Tornado component release provides many standard STREAMS features, as well as a number of enhancements to the AT&T UNIX System V Release 4 (SVR4) implementation.

WindNet STREAMS includes the following facilities:

• Interfaces available to network applications, including the native STREAMS interface, the Transport Library Interface (TLI), the X/Open Transport Interface (XTI), and a socket interface. (See §3.1 XTI/TLI Programming and §3.2 STREAMS Sockets Programming.)

• The Data Link Provider Interface (DLPI) driver, providing the development of a media-independent network protocol. (See §3.3 Data Link Provider Interface (DLPI) Driver.)

• The autopush utility for configuring streams. (See §3.4.1 The Autopush Utility.)

• The STREAMS Administration Driver (SAD) for maintaining autopush information. (See §3.4.1 The Autopush Utility.)

• Support for synchronization and four synchronization levels to facilitate operations in a multi-threaded environment. (See §4.1 The WindNet STREAMS Synchronization Model.)

• Support of streams pipes and FIFOs and the streams module pipemod, for communicating between tasks. (See §3.4.2 WindNet STREAMS Pipes and FIFOs.)

• Debugging utilities and routines, such as strace, strerr, and strlog( ). (See §5. WindNet STREAMS Debugging.)

Unsupported features are documented in §3.5 Unsupported Features.
