The help search path directs the desktop to search specified locations for files containing help information that will be registered on your system.
The default help search path includes personal, system-wide, and built-in locations. The default language is C.
Personal location—HomeDirectory/.dt/help
System-wide location—/etc/dt/appconfig/help/language
Built-in location—/usr/dt/appconfig/help/language
When a location is added to the application search path, the appropriate help subdirectory is automatically added to the help search path (see How the Application Search Path Affects the Database, Icon, and Help Search Paths).
For example, if the application server hosta: is added to the application search path, the directory hosta:/etc/dt/appconfig/help/language is automatically added to the help search path.
The help search path is assembled from the built-in locations and the following input variables:
DTSPSYSHELP
—system-wide
help search path input variable
DTSPUSERHELP
—personal
help search path input variable
Use these input variables to specify locations outside the application search path.
The assembled database search path is specified by the output variable DTHELPSEARCHPATH
.
The syntax for the variables DTSPSYSHELP
and DTSPUSERHELP
is:
VARIABLE=location [,location...]
where location can have the syntax:
/path—specifies a directory on the local (session server) system. Use this syntax to add a local directory.
To specify a location on another system, use its network file name—for example, /nfs/servera/projects/help.
The value of the help search path (DTHELPSEARCHPATH
) is created by assembling
the following locations, listed in order of precedence:
Locations specified using the DTSPUSERHELP
variable
Locations derived from the DTSPUSERAPPHOSTS
variable
The default personal location: HomeDirectory/.dt/help
The default location: /etc/dt/appconfig/help/language
Locations specified using the DTSPSYSHELP
variable
Locations derived from the DTSPSYSAPPHOSTS
variable
/usr/dt/appconfig/help/language
