    NAME
         DtEditorAppend - append data to a DtEditor widget
    
    SYNOPSIS
         #include <Dt/Editor.h>
         DtEditorErrorCode DtEditorAppend(Widget widget,
                                          DtEditorContentRec *data);
    
    DESCRIPTION
         The  DtEditorAppend()  function  appends  either   a   NULL-
         terminated  string,  wide  character  string or sized buffer
         after the last character in a DtEditor widget.  The data  is
         transferred  to  the DtEditor widget using a DtEditorConten-
         tRec, which indicates the type  of  data  being  transferred
         along with the actual data.  After the data is appended, the
         insertion cursor is positioned at the new last character.
    
         The widget argument specifies the DtEditor widget ID.
    
         The data argument points to the  data  structure  containing
         the data to append.
    
         For a complete definition of the  DtEditor  widget  and  its
         associated resources, see DtEditor(3).
    
         For  a  complete  definition  of   DtEditorContentRec,   see
         <Dt/Editor>.
    
    RETURN VALUE
         Upon successful completion,  the  DtEditorAppend()  function
         returns one of the following values:
    
            DtEDITOR_NO_ERRORS
                  The data was appended sucessfully.
    
            DtEDITOR_NULLS_REMOVED
                  NULL characters were found  and  removed  from  the
                  data.
    
         Otherwise, if the DtEditorAppend()  function  cannot  append
         the  data  into  the  DtEditor widget, it returns one of the
         following values:
    
            DtEDITOR_INVALID_TYPE
                  The type field is unrecognized.
    
            DtEDITOR_ILLEGAL_SIZE
                  The size of the buffer passed in is negative.
    
            DtEDITOR_NULL_ITEM
                  The buffer is NULL.
    
            DtEDITOR_INSUFFICIENT_MEMORY
                  Not enough system memory is available to append the
                  data.
    
    EXAMPLES
         The following code segment sets the contents of  a  DtEditor
         widget to ``The quick brown fox.''
    
              Widget                  editor;
              DtEditorContentRec      cr;
              DtEditorErrorCode       status;
              char                    *sampleString1="The quick",
                                      *secondString2=" brown fox";
              cr.type = DtEDITOR_TEXT;
              cr.value.string = sampleString1;
              status = DtEditorSetContents(editor, &cr);
              if (status != DtEDITOR_NO_ERRORS && status != DtEDITOR_NULLS_REMOVED) {
                      printf("Unable to set the contents of the widget\n");
              } else {
                      cr.type = DtEDITOR_TEXT;
                      cr.value.string = sampleString2;
                      status = DtEditorAppend(editor, &cr);
                      if (status != DtEDITOR_NO_ERRORS)
                              printf("Unable to append to the contents of the widget\n");
              }
    
    APPLICATION USAGE
         If the data is in a disk file, rather than  in  memory,  the
         application should use DtEditorAppendFromFile(3).
