32 .Nd System V STREAMS networking ABI support
34 To link System V Release 4 (SVR4) STREAMS interprocess communication ABI
35 support into the kernel:
36 .Cd pseudo-device streams
38 To load the SVR4 STREAMS interprocess communication ABI support kernel
44 module provides limited
45 System V Release 4 STREAMS interprocess communication ABI
46 (application binary interface) compatibility
47 for userland applications.
51 provides STREAMS handles by using socket creation kernel routines, and
52 adding state-tracking information to the socket to permit manipulation
53 by STREAMS emulation code in
55 Hence, opening a stream device produces a result similar to what would be
59 Applications should never use this interface directly: STREAMS
60 emulation is only provided as a service to support ABI requirements in
61 the SVR4 environment which
63 needs to present to client binaries.
67 System V Release 4 ABI support first appeared in
69 The ABI was ported from an equivalent facility present in
71 written by Christos Zoulas.
73 This whole interface is a crude hack to produce STREAMS semantics
74 through emulation over sockets.
76 Programmers who hope to be able to use this interface to provide
77 SVR4 STREAMS services to
79 applications will be sorely disappointed.
