Example

This program segment displays a topic with the ID getting-started in the volume MyVolume.

ac = 0;

XtSetArg (al[ac], DtNhelpType,   DtHELP_TYPE_TOPIC);  ac++;
 XtSetArg (al[ac], DtNhelpVolume,  "MyVolume");         ac++;
 XtSetArg (al[ac], DtNlocationId,  "getting-started");  ac++;
 XtSetArg (al[ac], DtNcolumns,    40);                  ac++;
 XtSetArg (al[ac], DtNrows,       12);                  ac++;
 XtSetValues (helpDialog, al, ac);
 XtManageChild (helpDialog);

If the help volume MyVolume is not registered, then a complete path to the MyVolume.sdl file is required for the value of DtNhelpVolume.
