XtCallActionProc(3Xt)XtCallActionProc(3Xt)NAME
XtCallActionProc - invoke an action procedure directly
SYNOPSIS
void XtCallActionProc(widget, action, event, params, num_params)
Widget widget;
String action;
XEvent* event;
String* params;
Cardinal num_params;
ARGUMENTS
Specifies the widget in which the action is to be invoked. Must be of class core of any subclass thereof. Specifies the name of the
action routine. Specifies the contents of the event passed to the action routine. Specifies the contents of the params passed to the
action routine. Specifies the num of entries in params.
DESCRIPTION
XtCallActionProc searches for the named action routine in the same manner and order as translation tables are bound. If found, the action
routine is invoked with the specified widget, event pointer, and parameters. It is the responsibility of the caller to ensure that the
contents of event, params, and num_params arguments are appropriate for the specified routine, and if necessary, that the specified widget
is realized or sensitive. If the named action routine cannot be found, XtCallActionProc generates a warning message and returns.

Name
XtCallActionProc - explicitly invoke a named action procedure.
Synopsis
void XtCallActionProc(widget, action, event, params, num_params)
Widget widget;
String action;
XEvent *event;
String *params;
Cardinal num_params;
Inputs
widget Specifies the widget in which the action is to be invoked; must be of class Core or any subclass thereof.
action Specifies the name of the action routine.
event Specifies the event to pass to the action procedure.
params Specifies parameters to pass to the action procedure.
num_params
Specifies the number of elements in the params array.
Description
XtCallActionProc() looks up the action procedure named action and invokes it, passing widget, event, params, and num_params as arguments.
Before calling the named action, XtCallActionProc() invokes any action hook procedures that have been registered with XtAppAddActionHook().
It is the responsibility of the caller to ensure that the contents of the event, params, and num_params arguments are appropriate for the
specified action routine and, if necessary, that the specified widget is realized and/or sensitive. If the named action routine cannot be
found, XtCallActionProc() generates a warning message and returns.
When searching for the action procedure, XtCallActionProc() looks in the following places:
o The widget's class and all superclass action tables, in subclass-to-superclass order.
o The parent's class and all superclass action tables, in subclass-to-superclass order, then on up the ancestor tree.
o The action tables registered with XtAppAddActions() and XtAddActions() from the most recently added table to the oldest table.

Hi Folks,
Today hasn't been the best one of my career in IT.
I've been a contractor for a major utility company for a number of years, on a number of seperate IT contracts mostly Unix. The company had 10 different flavours of unix and multiple different varsions of most of them.
