LOCAL FUNCTION
- save_inferior_pid - Save inferior_pid on the cleanup list
- restore_inferior_pid - Restore inferior_pid from the cleanup list
+ save_inferior_ptid - Save inferior_ptid on the cleanup list
+ restore_inferior_ptid - Restore inferior_ptid from the cleanup list
SYNOPSIS
- struct cleanup *save_inferior_pid ()
- void restore_inferior_pid (int pid)
+ struct cleanup *save_inferior_ptid ()
+ void restore_inferior_ptid (int pid)
DESCRIPTION
- These two functions act in unison to restore inferior_pid in
+ These two functions act in unison to restore inferior_ptid in
case of an error.

these routines before calling functions in procfs.c. In order to
- guarantee that inferior_pid gets restored (in case of errors), you

+ guarantee that inferior_ptid gets restored (in case of errors), you

function, you should invoke do_cleanups to restore it.
