    NAME
         Tcl_SaveResult, Tcl_RestoreResult, Tcl_DiscardResult -  save
         and restore an interpreter's result
    
    SYNOPSIS
         #include <tcl.h>
    
         Tcl_SaveResult(interp, statePtr)
    
         Tcl_RestoreResult(interp, statePtr)
    
         Tcl_DiscardResult(statePtr)
    
    ARGUMENTS
         Tcl_Interp        *interp    (in)      Interpreter for which
                                                state    should    be
                                                saved.
    
         Tcl_SavedResult   *statePtr  (in)      Pointer  to  location
                                                where     interpreter
                                                result   should    be
                                                saved or restored.

    DESCRIPTION
         These routines allows a C procedure to take  a  snapshot  of
         the  current  interpreter  result so that it can be restored
         after a call to Tcl_Eval or some other routine that modifies
         the interpreter result.  These routines are passed a pointer
         to a structure that is used to store enough  information  to
         restore the interpreter result state.  This structure can be
         allocated on the stack of the calling procedure.  These rou-
         tines  do not save the state of any error information in the
         interpreter (e.g. the errorCode or errorInfo variables).
    
         Tcl_SaveResult moves the string and object results of interp
         into  the  location  specified  by statePtr.  Tcl_SaveResult
         clears the result for interp and leaves the  result  in  its
         normal empty initialized state.
    
         Tcl_RestoreResult moves the string and object  results  from
         statePtr  back  into  interp.   Any result or error that was
         already in the interpreter will be cleared.  The statePtr is
         left  in  an  uninitialized  state  and cannot be used until
         another call to Tcl_SaveResult.
    
         Tcl_DiscardResult  releases  the  saved  interpreter   state
         stored at statePtr.  The state structure is left in an unin-
         itialized state and cannot be used  until  another  call  to
         Tcl_SaveResult.
    
         Once  Tcl_SaveResult  is  called  to  save  the  interpreter
         result,  either  Tcl_RestoreResult or Tcl_DiscardResult must
         be called to properly clean up the  memory  associated  with
         the saved state.
