NAME

       ncad_addr - name of the Solaris Network Cache and Accelerator (NCA) socket utility library

SYNOPSIS

       /usr/lib/ncad_addr.so

DESCRIPTION

       ncad_addr.so is the Solaris Network Cache and Accelerator (NCA) socket utility library. Use this library with a web server to avoid support
       for the PF_NCA family type socket. The web server can take advantage of NCA functionality.

       Interpose the ncad_addr interfaces before the interfaces in libsocket by setting the environment variable  LD_PRELOAD  to  ncad_addr.so	so
       that it is preloaded before libsocket.so.1. The ncad_addr.so interfaces will be interposed only if NCA is enabled. See ncakmod(1).

EXAMPLES

       Example 1: Interposing ncad_addr

       Using Bourne shell syntax as an example, set LD_PRELOAD as shown below to interpose the ncad_addr socket utility libary:

       LD_PRELOAD=/usr/lib/ncad_addr.so /usr/bin/httpd

FILES

       /usr/lib/ncad_addr.so   ncad_addr socket utility library shared object
