My problem is this:

Hi
Our problem is knowing:
What is the "best" way of simulating a TRAP for ERR within a function, since we know this will not work directly with ksh93 and aix5. How can we save the error encountered in the function and then deal with it in the calling script?
Thanks! (3 Replies)

ncad_addr
ncad_addr(4) File Formats ncad_addr(4) 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
