Chapter 1: Quick Start
This section of the manual will get you using ZeroFault as quickly as possible. We highly recommend that you do read the other sections of the manual, but you should be able to start getting benefits from ZeroFault within minutes of installing it.
If you haven't already installed ZeroFault, then please follow the instructions in the installation section.
- Add the ZeroFault binary directory to your PATH environment variable
if you installed ZeroFault into /usr/local/zf instead
of the default installation directory (/usr/lpp/ZeroFault),
and if you use the Korn Shell (/bin/ksh), at the
shell prompt you would type
the zf command (and any arguments to zf)
in front of the command you would normally execute to start
your application. For example:
zf /u/me/bin/myprogram -myflag myarg1 myarg2
zf -d creek:0 vi /etc/motd
best with the graphical user interface (GUI), and you should run
ZeroFault from a graphical workstation until you become familiar
with using it. Users who must run ZeroFault without the graphical
interface should familiarize themselves with the zf_rpt
When using ZeroFault
with the GUI, the GUI window
will appear after a short time (if this doesn't happen,
you probably don't have your DISPLAY value set properly),
help pages are available from the Help menu in the upper-right hand
corner of the main window.
errors in an outline form in the main error pane (the one with the
white background). Lines that begin with an arrow are individual
messages; those that begin with a box represent a group of similar
messages that are condensed. By default, errors are displayed in
a summary (collapsed) form, with their details hidden; they can
be easily expanded to show memory locations, detailed tracebacks,
- The acronyms
in all capital letters are memory error types.
- To view individual
errors that are condensed (in lines that begin with a box), click
the left mouse button anywhere on the condensed message. This
"peels off" and expands a message from the group of similar messages.
To collapse an expanded message and condense it back into a group
of similar messages, click the left button anywhere on its first
line. Individual error messages and error tracebacks in an expanded
error message can also be expanded and collapsed in the same way.
- You can view
the source file associated with an error if it has a quoted filename
displayed in the expanded traceback. Hold down the Shift key and
click the left mouse button over the line, and the source code
will appear in the source (bottom) pane. When an error is expanded,
the source pane will automatically display the source code for
the error if it is available (if the source file isn't found,
see Viewing Source for information
on specifying a source path to ZeroFault).
- To inspect
the application for memory leaks, press the Find Leaks button.
ZeroFault displays a list of the allocated memory blocks in the
program that are not currently referenced by any pointer. For
more information see Finding Memory Leaks.
- Use the Sort
by and Condense by menus and the message filtering function to
change the order and appearance of the error messages. See Viewing Error Messages
for more information.
