Accessing HP C Online Help
To access the HP C Online Help, you must be logged onto a system where the most recent
version of the HP C compiler is installed. Typing the following at the command line invokes
an HTML browser, which displays the main HTML index file for the HP C Online Help
system:
/opt/ansic/bin/cc +help
The actual location of the HTML files is:
file:/${CROOTDIR}/html/guide/${LOCALE}/c_index.html.
If the environment variable CROOTDIR is not set, the path will be formed relative to the
compiler’s root directory; this is usually /opt/ansic. The previous section contains
instructions on how to set CROOTDIR.
NOTE 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, then you must set the BROWSER
environment variable appropriately.
