| 73 | save_inferior_pid - Save inferior_pid on the cleanup list |

| 76 | SYNOPSIS |
| 77 | |
| 78 | struct cleanup *save_inferior_pid () |
| 79 | void restore_inferior_pid (int pid) |
| 80 | |
| 81 | DESCRIPTION |
| 82 | |
| 83 | These two functions act in unison to restore inferior_pid in |
| 84 | case of an error. |
| 85 | |
| 86 | NOTES |
| 87 | |
| 88 | inferior_pid is a global variable that needs to be changed by many of |
| 89 | these routines before calling functions in procfs.c. In order to |
| 90 | guarantee that inferior_pid gets restored (in case of errors), you |
| 91 | need to call save_inferior_pid before changing it. At the end of the |
| 92 | function, you should invoke do_cleanups to restore it. |
