You can order printed versions of a wide variety of Hewlett-Packard documents. Use the man manuals command for details on which documents are available for ordering as well as ordering information. See also the HP documentation web site http://docs.hp.com and the HP C/HP-UX web site at http://www.hp.com/go/C. Listed below are some of the documents most closely related to use of the C Compiler.

HP C Online Help

The C compiler online help includes examples, tutorial information, error message discussions, and reference information.

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

cc +help

or

/usr/dt/bin/dthelpview -h c

and the online help window appears on your display. (Note that this requires that your $DISPLAY variable is set correctly. If you do not know how to do this, contact your system administrator.)

You can also click on the ? icon on the HP CDE front panel on a system where HP C is installed and select HP C Online Reference.

If you do not have a graphics display or prefer to work with a character-based help interface, enter the command:

charhelp

and you will get a usage description for this command:

charhelp: Usage: charhelp {cc|CC|aCC|f77|ld|dde| -helpVolume file}

For help with the HP C compiler, for example, enter:

charhelp cc

and follow the menus for further direction. The charhelp command is in the directory /opt/langtools/bin. For more information, see the man page for charhelp(1) (/opt/langtools/share/man/man1.Z must be in your $MANPATH environment variable).
