DESCRIPTION
The dthelpprint utility is a private utility used by DtHelp-
Dialog(3) and DtHelpQuickDialog(3) for printing Help
information. It is not a public utility, and no effort to
maintain backwards compatibility will be made across ver-
sions. That said, it is sometimes useful to use dthelpprint
directly and to configure its operation.
The dthelpprint utility processes help topics and can send
the output to a printer or to a specified output file. The
dthelpprint utility is an integral part of the CDE Help Sys-
tem. Access to dthelpprint is provided by the dthelpview(1)
client's Print dialog, an application's Help window, or
through a utility line shell.
The dthelpprint utility can print plain text strings, plain
text files, Unix man pages, and CDE Help volumes. CDE Help
volumes are printed without any graphics, and there is no
indication of missing graphics. The standard man(1) and
dthelpview(1) search paths are used to find manual pages and
CDE Help volumes; Help volumes and files may be specified
with an absolute pathname.
OPTIONS
The dthelpprint utility has two sets of utility line
options. The first set controls what should be printed.
The second set controls how it should be printed. All
option names must be used exactly as given. An alternative
to specifying options on the utility line is to specify them
using resources in an app-defaults file. This is useful for
changing the default values from those given below. See the
RESOURCE OVERVIEW heading in this manual page for more
information.
Options controlling what to print:
-helpType type
The type of Help data to print. This is a numeric
value, as follows: 0=help volume, 1=string, 2=man
page, 3=help file. The default value is 0, a Help
volume.
-helpVolume volume
The name of the volume holding the topics to be
printed. If volume is unqualified, the standard
dthelpview(1) search paths are used to locate the
volume; these are also covered in the ENVIRONMENT
VARIABLES heading in this manual page. The volume
may also be specified relative to the current
directory by beginning the volume name with "./" or
"../". This option is useful only in conjunction
with a -helpType of 0 (zero).
-locationId location
The starting topic for processing topics of a Help
volume. The location must be a text string used by
the author to mark a location in the volume. The
default value is _hometopic, which is the top topic
of a CDE Help volume. This option is useful only
in conjunction with -helpVolume.
-allTopics
Instructs dthelpprint to print the entire help
volume, including front matter, table of contents,
all topics, and an index. This option is useful
only in conjunction with -helpVolume.
-subTopics
Instructs dthelpprint to print the topic specified
by -locationId and all the subtopics of that topic.
This option is useful only in conjunction with
-helpVolume.
-oneTopic
Instructs dthelpprint to print the topic specified
by -locationId. This option is useful only in con-
junction with -helpVolume.
-toc Instructs dthelpprint to print the Table of Con-
tents of the specified helpVolume. This option is
useful only in conjunction with -helpVolume.
-index
Instructs dthelpprint to print the Index of the
specified helpVolume. This option is useful only
in conjunction with -helpVolume.
-frontMatter
Instructs dthelpprint to print the front matter of
the specified helpVolume. Front matter includes
the volume title, abstract, and copyright informa-
tion. This option is useful only in conjunction
with -helpVolume.
-stringData string
Specifies a string to print. This option is useful
only in conjunction with a -helpType of 1.
-manPage manpagename
Specifies the name of the Unix man page to print.
This option is useful only in conjunction with a
-helpType of 2.
-helpFile filename
Specifies a file to print. This option is useful
only in conjunction with a -helpType of 3.
Options controlling how to print:
-printer printername
Specifies which printer to use. If this isn't speci-
fied as a utility-line option or resource, the default
value is taken from the environment variable LPDEST.
-copies number
Specifies how many copies to produce. The default
value is 1. This option is only ignored when generat-
ing an output file.
-outputFile filename
Specifies a file to hold the print-ready output. If
this option is specified, no output is sent to the
printer.
-paperSize size
Specifies a size of paper to which the output should
be formatted. There are five valid values for size:
help_papersize_letter, help_papersize_legal,
help_papersize_executive, help_papersize_a4,
help_papersize_b5. The default value is
help_papersize_letter.
-display displayname
Specifies the X display used to retrieve resource
values. Typical format for displayname is
hostname:display_number.screen_number. If no screen
number is specified, the first screen (0) is used.
See also X(1)
-name name
Specifies the application name under which resources
are to be obtained. The default is dthelpprint. The
resource application.name way also be used to specify
the name.
-class classname
Specifies the application class name under which
resources are to be obtained. The default is dthelp-
print. The resource application.class may also be
used to specify the class name.
-xrm resourcestring
Specifies an addition to the resource database used by
this invocation of the program.
RESOURCE OVERVIEW
The dthelpprint utiity uses resources in addition to
utility-line options to configure its operation. There are
many more resources available for this purpose than
utility-line options. To set a resource on the utility
line, use the -xrm option.
The application class is dthelpprint unless specified other-
wise with the application.class or Application.Class
resources or the -class option. The application instance
name is the name used to run the program (usually dthelp-
print) unless specified otherwise with the application.name
or Application.Name resource or the -name option. In the
following coverage of resource specifications, the
application's class name and instance name can be used
interchangably; however, if the same resource is specified
more than once, the instance-specific resource takes pre-
cedence over the class resource. In addition, when a value
can be specified using either a resource or utility-line
option, the utility-line option value takes precedence.
The dthelpprint utility has three types of resources.
Help Content These resoures specify what to print.
Typically, these values are specified
using utility-line options instead of
resources.
Content Processing
These resources specify in more detail the
configuration of how to print. These
resources include some values that can be
specified with utility-line options, but
also many others.
Printer Configuration:
The dthelpprint utility allows printer-
specific configurations to be specified.
The configuration used is controlled by
the value of the printer resource or
-printer option.
HELP CONTENT RESOURCES
These resources specify what to print. The syntax for
specifying the resources is
Dthelpprint*resource:resource value
For example, Dthelpprint*helpVolume: aVolume.sdl is used to
specify the name of the Help volume.
Basic Resource Set
Name Class Type Default
____________________________________________________________
locationId LocationId string _HOMETOPIC
helpVolume HelpVolume string NULL
manPage ManPage
stringData StringData string NULL
helpFile HelpFile string NULL
topicTitle TopicTitle string NULL
helpType HelpType string NULL
These Help-content resources are defined in DtHelpDialog(3).
The following content options are specific to dthelpprint.
Setting the resource to any value makes it True.
Additional Resource Set

allTopics AllTopics string NULL
subTopics SubTopics string NULL
oneTopic OneTopic string NULL
toc Toc string NULL
index Index string NULL
frontMatter FrontMatter string NULL
These Help-content resources have the same meaning as the
dthelpprint utility-line options of the same name.
HELP PROCESSING RESOURCES
These resources specify how to print. The syntax for speci-
fying the resources is:
Dthelpprint*resource:resource value
For example, Dthelpprint*printer: aPrinter is used to
specify the name of the printer.
Basic Resource Set
Name Class Type Default
____________________________________________________________
printer Printer string NULL
copies Copies string NULL
outputFile OutputFile string NULL
paperSize PaperSize string NULL

The values of these resources are used as the header and
footer strings only when printing Help volumes. Header and
footer strings are specified separately for odd and even
pages to support double sided printing. The strings may
contain symbolic names for dynamic values.
Dynamic values are updated each time the string is to be
used. Valid dynamic values are as follows:
Symbol Value
______________________________________________________________________
$LMARGIN left margin blanks.
$TODAY today's date.
$VOLDATE date on the help volume file.
$VOLUME volume name.
$VOLUMEFILL filler for fixed sized 50 column volume name.
$TOPIC section topic title.
$TOPICFILL filler for fixed sized 50 column section topic title.
$PAGENUM page number.
$PAGENUMFILL filler for fixed sized 3 column page number.
$SECTNUM section number or name.
$SECTNUMFILL filler for fixed sized 8 column section number or name.
The default values for the resources are as follows (To
improve understanding, the blank spaces have been replaced
with '.'.):
evenTocHeader and oddTocHeader:
$LMARGIN$VOLUME\n\n
evenTocFooter and oddTocFooter:
\n$LMARGIN......................................................$SECTNUM
evenBodyHeader and oddBodyHeader:

PRINTER CONFIGURATION RESOURCES
These resources specify printer configuration. This
includes a default configuration as well as printer-specific
configurations. The syntax for specifying the resources is
Dthelpprint*printer.resource:resource value
Dthelpprint*printer.printerName.resource:resource value
For example,
Dthelpprint*printer.paperSize: help_papersize_legal
help_papersize_executive
Dthelpprint*printer.laser-c4.paperSize:
set the default paper size to legal and the paper size on
the printer named "laser-c4" to executive.
Basic Resource Set
Name Class Type Default
______________________________________________________________________
paperSize PaperSize String help_papersize_letter
colsWidth ColsWidth Int 0
rowsHeight RowsHeight Int 0
colsLeftMargin ColsLeftMargin Int 10
colsRightMargin ColsRightMargin Int 10
rowsTopMargin RowsTopMargin Int 6
rowsBottomMargin RowsBottomMargin Int 6
These resources are used to specify the printer configura-
tion, specifically with respect to the paper used for print-
ing. Paper size can be specified either by using the paper-
Size resource or by setting an explicit size with the
colsWidth and rowsHeight resources. The margin values
specify the amount of white space retained around the page.
paperSize This resource can be used to set the paper
size to predefined dimensions. Valid
values are help_papersize_letter, (8.5 x
11 in; 69 rows x 91 cols)
help_papersize_legal, (8.5 x 14 in; 88
rows x 91 cols) help_papersize_executive,
(7.25 x 10.5 in, 66 rows x 77 cols)
help_papersize_a4, (210 x 297 mm, 73 rows
x 88 cols) and help_papersize_b5 (182 x
257 mm, 63 rows x 76 cols). If these
dimensions are insufficient, the colsWidth
and rowsHeight resources can be used to
provide explicit dimensions. All dimen-
sions are given in columns and rows of
text in the default printer font.
colsWidth Width of the paper in columns of charac-
ters in the default printer font. The
value may not be 0 (zero).
rowsHeight Height of the paper in rows of text in the
default printer font. The value may not
be 0 (zero).
colsLeftMargin Width of the left margin in columns of
characters in the default printer font.
colsRightMargin
Width of the right margin in columns of
characters in the default printer font.
rowsTopMargin Height of the top margin in rows of text
in the default printer font.
rowsBottomMargin
Height of the bottom margin in rows of
text in the default printer font.
ENVIRONMENT VARIABLES
The CDE Help system uses two environment variables for
locating Help volumes files within the desktop environment:
DTHELPSEARCHPATH
System search path environment variable
for locating Help volumes on local and/or
remote nfs mounted systems.
DTHELPUSERSEARCHPATH
Users search path environment variable for
locating user specific Help volumes on
local and/or remote nfs mounted systems.
Refer to DtHelpDialog(3) or DtHelpQuickDialog(3) for infor-
mation of setting the DTHELP environment variables.
INPUT FILES
The following are input files and resource databases are
merged by dthelpprint to construct the complete resource
database used by the program. Resource collisions are
resolved by having the last value take precedence.
/usr/dt/app-defaults/C/Dthelpprint
/usr/lib/X11/app-defaults/Dthelpprint
$HOME/Dthelpprint
display resources or $HOME/.Xdefaults
screen resources
$XENVIRONMENT or $HOME/.Xdefaults-<hostname>
utility-line resources
OUTPUT FILES
The dthelpprint utility always generates an output file,
either for sending to the printer or to place in a user-
specified file.
$HOME/.dt/tmp/phlp<process id>_<cnt>.txt
These are the temporary files generated by
the dthelpprint utility. These files are
placed under the user's directory so that
remote systems can reach the file via NFS.
$PWD/db.dthelpprint
This file is generated in the current
directory when the debugHelpPrint resource
is defined. The file constains the com-
plete set of resources used by dthelpprint
to configure its operation.
Warning Messages
