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:

    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 DtEditorReplace(3).
