     NAME
          Dt/Dt.h - miscellaneous desktop definitions

     SYNOPSIS
          #include <Dt/Dt.h>

     DESCRIPTION
          The <Dt/Dt.h> header contains miscellaneous public constant
          and function declaration for the CDE library.

          The header defines several constants that can be used to
          determine the version of the library used to compile an
          application and the version of the library with which an
          application is currently linked.

          The header defines the following constants that represent
          the library compile-time version:

             DtVERSION               An integer specifying the major
                                     version number

             DtREVISION              An integer specifying the minor
                                     version number

             DtUPDATE_LEVEL          An integer specifying the patch
                                     release level

             DtVERSION_NUMBER        An integer combining the major,
                                     minor and patch release numbers.
                                     It is derived from the following
                                     formula:

                                          (10000 * DtVERSION + 100 *
                                           DtRevision + DtUPDATE_LEVEL)

             DtVERSION_STRING        A string containing a description
                                     of the version and the version
                                     number

          The header defines the following constants that represent
          the library run-time version:

          extern int DtVersion
          extern char *DtVersionString

          DtVersion is an integer equivalent to DtVERSION_NUMBER at
          the time the library was created.  DtVersionString is a
          string equivalent to DtVERSION_STRING at the time the
          library was created.

          The header declares the following as functions:
          Boolean DtInitialize(Display *display,
                               Widget widget,
                               char *name,
                               char *tool_class)

          Boolean DtAppInitialize(XtAppContext app_context,
                                  Display *display,
                                  Widget widget,
                                  char *name,
                                  char *tool_class)
