NAME
     DtEditorReplaceFromFile - replace a portion of the  contents
     of a DtEditor widget with the contents of a file

SYNOPSIS
     #include <Dt/Editor.h>
     DtEditorErrorCode DtEditorReplaceFromFile(Widget widget,
                                               XmTextPosition startPos,
                                               XmTextPosition endPos,
                                               char *fileName);

DESCRIPTION
     The DtEditorReplaceFromFile() function replaces part of  the
     contents  of  a DtEditor widget with the contents of a file.
     All data following the start position and  up  to,  but  not
     including, the end position is replaced.  If the start posi-
     tion and the end position are equal, the  data  is  inserted
     after  the  end  position.  The character positions begin at
     zero and are numbered sequentially from the beginning of the
     text.   After the replacement, the insertion cursor is posi-
     tioned after the last character inserted.

     The widget argument specifies the DtEditor widget ID.

     The startPos argument specifies the starting character posi-
     tion  of  the portion to replace.  The replacement begins at
     this character.

     The endPos argument specifies the ending character  position
     of the portion to replace.  The replacement ends before this
     character.

     The fileName argument is the pathname of the  file  relative
     to the local system.

     For a complete definition of the  DtEditor  widget  and  its
     associated resources, see DtEditor(3).

RETURN VALUE
     Upon successful  completion,  the  DtEditorReplaceFromFile()
     function returns one of the following values:

        DtEDITOR_NO_ERRORS
              The file is readable and writable.

        DtEDITOR_READ_ONLY_FILE
              The file is read only.

        DtEDITOR_NULLS_REMOVED
              The file contained embedded NULL characters,  which
              were removed.

     Otherwise, if it cannot insert the data  into  the  DtEditor
     widget, the function returns one of the following values:

        DtEDITOR_INVALID_RANGE
              The startPos argument is greater  than  the  endPos
              argument.

        DtEDITOR_MAX_SYM_LINKS
              The maximum number of symbolic links  (MAXSYMLINKS)
              was exceded before the actual file could be found.

        DtEDITOR_NONEXISTENT_FILE
              The file does not exist.

        DtEDITOR_DIRECTORY
              The file is a directory.

        DtEDITOR_CHAR_SPECIAL_FILE
              The file is a character-special device.

        DtEDITOR_BLOCK_MODE_FILE
              The file is a block-mode device.

        DtEDITOR_NO_FILE_ACCESS
              The file cannot be accessed.

        DtEDITOR_INSUFFICIENT_MEMORY
              Not enough system memory is  available  to  replace
              the data.

        DtEDITOR_UNREADABLE_FILE
              The file is unreadable for an unspecified reason.

APPLICATION USAGE
     If the data is in memory,  rather  than  a  disk  file,  the
     application should use DtEditorReplace(3).
