HP C B.11.11.16 Release Notes

HP C/ANSI C Release Notes

Documentation Overview

Chapter 1 23

You may set the CROOTDIR environment variable to set the root directory of the online help

source. If CROOTDIR is not set, the URL of the online help will be

file:/opt/ansic/html/guide/${LOCALE}/c_index.html ; this is assuming that compiler

binaries are located in /opt/ansic/bin.

Accessing HP C Online Help

To access the online help, on a system where the HP C compiler is installed, enter the

following:

/opt/ansic/bin/cc +help

This command will launch a web browser, displaying the index ﬁle for the HP C online help

system. The actual ﬁle location of the html help is

file:/${CROOTDIR}/html/guide/${LOCALE}/c_index.html.

If the environment variable CROOTDIR is not set, path will be formed relative to the compiler’s

root directory; this is usually /opt/ansic. See for more information on setting the CROOTDIR

environment variable.

If the browser path set by the BROWSER environment variable does not exist, or if the default

browser paths /opt/ns-navgold/bin/netscape or /opt/ns-communicator/netscape do

not exist, a message is displayed telling you that the BROWSER environment variable must be

set properly.

X-Motif CDE Help is Obsolete

Previous versions of the HP C compiler, when installed on the X-Motif CDE environment,

included a CDE version of the online help. This and the accompanying text-based charhelp

will no longer be updated with the ANSI C compiler. If you want to view online help, please

use the HP C HTML Online Help.
