If I forget to set up stderr redirection on execution of a script, is there a way to set that redirection post-exec? In other words, if I have a script running and no errors are being logged... and then I remember that I forgot the 2>&1 on the script... can I turn it on after the fact?

XtErrorHandler() XtErrorHandler()
Name
XtErrorHandler - interface definition for low-level error and warning handler procedures.
Synopsis
typedef void (*XtErrorHandler)(String);
String message;
Inputs
message Specifies the error message.
Description
An XtErrorHandler is registered as an error or warning handler with XtAppSetErrorHandler() or XtAppSetWarningHandler(). It is invoked by
XtAppError() or XtAppError(). The error handler should display the specified string in some appropriate fashion. Some applications may
wish to log errors to a file as well. Error handlers should exit; warning handlers should return.
See XtErrorMsgHandler(2) for a description of the high-level error and warning handler procedure.
Example
The Intrinsics default error and warning handlers are shown below. The XTERROR_PREFIX and XTWARNING_PREFIX symbols are by default the
empty string in the MIT implementation, but may be configured when the Intrinsics are compiled.
void _XtDefaultError(message)
String message;
{
extern void exit();
(void)fprintf(stderr, "%sError: %s0, XTERROR_PREFIX, message);
exit(1);
}
void _XtDefaultWarning(message)
String message;
{
if (message && *message)
(void)fprintf(stderr, "%sWarning: %s0, XTWARNING_PREFIX, message);
return;
}
