XtCallCallbacks, XtCallCallbackList, XtHasCallbacks - process callbacks
SYNTAX
void XtCallCallbacks(Widget w, String callback_name, XtPointer call_data);
void XtCallCallbackList(Widget w, XtCallbackList callbacks, XtPointer call_data);
typedef enum {XtCallbackNoList, XtCallbackHasNone, XtCallbackHasSome} XtCallbackStatus;
XtCallbackStatus XtHasCallbacks(Widget w, String callback_name);
ARGUMENTS
callback_name
Specifies the callback list to be executed or checked.
call_data Specifies a callback-list specific data value to pass to each of the callback procedure in the list.
callbacks Specifies the callback list to be executed.
w Specifies the widget.
DESCRIPTION
The XtCallCallbacks function calls each procedure that is registered in the specified widget's callback list.
If callbacks is not NULL, XtCallCallbackList calls each of the callback procedures in the list, passing client data and call_data. The
callbacks parameter must specify the contents of a widget or object resource declared with representation type XtRCallback.
The XtHasCallbacks function first checks to see if the widget has a callback list identified by callback_name. If the callback list does
not exist, XtHasCallbacks returns XtCallbackNoList. If the callback list exists but is empty, it returns XtCallbackHasNone. If the call-
back list exists and has at least one callback registered, it returns XtCallbackHasSome.

I used to use ls -l cut to detrmine file size, and google searches didn't come up with anything else but 'stat' which doesn't appear on HPUX.
I discovered the humble 'wc -c' which does this job very neatly, and thought I would share it. (7 Replies)

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
