DtEditorReplaceFromFile(3)

     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 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

             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_NONEXISTENT_FILE
                   The file does not exist.

             DtEDITOR_CHAR_SPECIAL_FILE
                   The file is a character-special device.

             DtEDITOR_BLOCK_MODE_FILE

             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).
