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 position 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 positioned after the last character
  inserted.

  The widget argument specifies the DtEditor widget ID.

  The startPos argument specifies the starting character position 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 DtEditor3.

RETURN VALUE
  Upon successful completion, the DtEditorReplaceFromFile function returns
  one of the following values:
  The file is readable and writable.
  The file is read only.
  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:
  The startPos argument is greater than the endPos argument.
  The file does not exist.
  The file is a directory.
  The file is a character-special device.
  The file is a block-mode device.
  The file cannot be accessed.
  Not enough system memory is available to replace the data.
  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 DtEditorReplace3.
