.TH NCAD_ADDR 4 "Feb 18, 2003"
.SH NAME
ncad_addr \- name of the Solaris Network Cache and Accelerator (NCA) socket
utility library
.SH SYNOPSIS
.LP
.nf
\fB/usr/lib/ncad_addr.so\fR
.fi

.SH DESCRIPTION
.sp
.LP
\fBncad_addr.so\fR is the Solaris Network Cache and Accelerator (\fBNCA\fR)
socket utility library. Use this library with a web server to avoid support for
the \fBPF_NCA\fR family type socket. The web server can take advantage of NCA
functionality.
.sp
.LP
Interpose the \fBncad_addr\fR interfaces before the interfaces in
\fBlibsocket\fR by setting the environment variable \fBLD_PRELOAD\fR to
\fBncad_addr.so\fR so that it is preloaded before \fBlibsocket.so.1\fR. The
\fBncad_addr.so\fR interfaces will be interposed only if NCA is enabled. See
\fBncakmod\fR(1).
.SH EXAMPLES
.LP
\fBExample 1 \fRInterposing \fBncad_addr\fR
.sp
.LP
Using Bourne shell syntax as an example, set \fBLD_PRELOAD\fR as shown below to
interpose the \fBncad_addr\fR socket utility libary:

.sp
.in +2
