NAME
       ReqErr - handle request errors

SYNOPSIS
       #include <InterViews/reqerr.h>

DESCRIPTION
       Some  requests  to  the window server may generate an error.  For example, if a window is destroyed while it is being repositioned interac-
       tively, the request to place the window in the new position will fail.  Normally, errors cause a process to terminate.  The ReqErr class is
       used  to handle errors within an application.  The base class defines the attributes associated with each error, including a message string
       describing the error, an integer request code that specifies the kind of call that generated the error, and a id object that was the target
       of  the	request.   When  an  error occurs, the attributes of the current request handler are assigned and the handler's Error operation is
       called.
