There is no "insert" operation for files, and never has been. Text editors and the like accomplish it by reading the entire file into memory then writing back the data they want. Anything after the change will have to be rewritten if the length changes. (The file might even need to be truncated, if it ended up shorter than before.)

XmTextReplaceWcs(3X) XmTextReplaceWcs(3X)
NAME
XmTextReplaceWcs - A Text function that replaces part of a wide character string in a Text widget
SYNOPSIS
#include <Xm/Text.h>
void XmTextReplaceWcs (widget, from_pos, to_pos, wcstring)
Widget widget;
XmTextPosition from_pos;
XmTextPosition to_pos;
wchar_t *wcstring;
DESCRIPTION
XmTextReplaceWcs replaces part of the wide character string in the Text widget. The character positions begin at zero and are numbered
sequentially from the beginning of the text.
An example text replacement would be to replace the second and third characters in the text string. To accomplish this, the from_pos
parameter must be 1 and the to_pos parameter must be 3. To insert a string after the fourth character, both the from_pos and to_pos param-
eters must be 4.
This routine calls the widget's XmNvalueChangedCallback and verification callbacks, either XmNmodifyVerifyCallback or XmNmodifyVerifyCall-
backWcs, or both. If both verification callback lists are registered, the procedures of the XmNmodifyVerifyCallback list are executed
first and the resulting data is passed to the XmNmodifyVerifyCallbackWcs callbacks. Specifies the Text widget ID Specifies the start posi-
tion of the text to be replaced Specifies the end position of the text to be replaced Specifies the wide character string value to be added
to the Text widget
