dthelpview - view a CDE help volume
The following options are available:
Specifies the name of the <filename>.sdl file you want to view. If
locationId is not set, the default _HOMETOPIC ID is used. If the
requested volume is in the current working directory, or the Help
volume has been properly registered, no path is required.
Specifies the location ID representing the desired Help topic to be
viewed. By default, Helpview uses _HOMETOPIC if an ID is not specified.
Specifies a particular ASCII text file to be displayed.
Specifies a particular man page to be displayed.
Displays a dialog that prompts for a man page to view, then displays
the requested man page.
The dthelpview utility supports the viewing of CDE online Help volumes,
ASCII files or manual pages. The dthelpview utility is an integral part of
the CDE application Help environment. The dthelpview utility's
functionality and user interface is almost completely that of the standard
CDE general Help and quick Help dialog widgets. (See DtCreateHelpDialog(3)
For information on Help dialog widget resources, refer to
DtCreateHelpDialog3 or DtCreateQuickHelpDialog3.
The dthelpview utility's specific resources set in the Dthelpview app-
defaults file are:
The CDE Help system uses two environment variables for locating Help
volumes and Family files within the desktop environment:
System search path environment variable for locating Help volumes on
local and remote nfs mounted systems.
Users search path environment variable for locating user specific Help
volumes on local and remote nfs mounted systems.
The environment variables contain colon-separated lists of directory paths.
Each directory path can contain both environment variable names as well as
special field descriptors that are expanded at runtime via each Help
component that uses these environment variables.
Field descriptors consist of a % followed by a single character. Field
descriptors and their substitution values are:
%H This value is replaced with the current volume name being searched for.
%L Replaced with the current value of the LANG environment variable.
%% Replaced with a single %.
The default value for DTHELPUSERSEARCHPATH is:
The DTHELPUSERSEARCH is first searched for the requested volume. If the
volume is not found, the DTHELPSEARCHPATH value is searched.
The default value for DTHELPSEARCHPATH path is:
dthelpview -helpVolume dtintro.sdl -locationId _hometopic
Displays the topic associated with _hometopic in the Help volume
dthelpview -file /etc/checklist
Displays the file /etc/checklist in a general Help dialog
dthelpview -man grep
