NAME



streams

 - System V STREAMS networking ABI support

SYNOPSIS

To compile support for this ABI into the kernel, place the following line in your kernel configuration file:

device streams

Alternatively, to load the ABI as a module at boot time, place the following line in loader.conf5:

streams_load="YES"

DESCRIPTION

The module provides limited System V Release 4 STREAMS interprocess communication ABI (application binary interface) compatibility for userland applications.

Internally, provides STREAMS handles by using socket creation kernel routines, and adding state-tracking information to the socket to permit manipulation by STREAMS emulation code in svr4(4). Hence, opening a stream device produces a result similar to what would be obtained by calling socket(2).

Applications should never use this interface directly: STREAMS emulation is only provided as a service to support ABI requirements in the SVR4 environment which svr4(4) needs to present to client binaries.

HISTORY

System V Release 4 ABI support first appeared in Fx 4.0 . The ABI was ported from an equivalent facility present in Nx 1.3 written by Christos Zoulas.
