+Routine Description:
+
+ This function virtually unwinds the specified function by executing its
+ prologue code backward or its epilogue code forward.
+
+ If a context pointers record is specified, then the address where each
+ nonvolatile registers is restored from is recorded in the appropriate
+ element of the context pointers record.
+
+Arguments:
+
+ HandlerType - Supplies the handler type expected for the virtual unwind.
+ This may be either an exception or an unwind handler. A flag may
+ optionally be supplied to avoid epilogue detection if it is known
+ the specified control PC is not located inside a function epilogue.
+
+ ImageBase - Supplies the base address of the image that contains the
+ function being unwound.
+
+ ControlPc - Supplies the address where control left the specified
+ function.
+
+ FunctionEntry - Supplies the address of the function table entry for the
+ specified function.
+
+ ContextRecord - Supplies the address of a context record.
+
+
+ HandlerData - Supplies a pointer to a variable that receives a pointer
+ the the language handler data.
+
+ EstablisherFrame - Supplies a pointer to a variable that receives the
+ the establisher frame pointer value.
+
+ ContextPointers - Supplies an optional pointer to a context pointers
+ record.
+
+ HandlerRoutine - Supplies an optional pointer to a variable that receives
+ the handler routine address. If control did not leave the specified
+ function in either the prologue or an epilogue and a handler of the
+ proper type is associated with the function, then the address of the
+ language specific exception handler is returned. Otherwise, NULL is
+ returned.
