c5aa993b | 83 | SYNOPSIS |
c906108c | 84 | |
39f77062 KB |
85 | struct cleanup *save_inferior_ptid () |
86 | void restore_inferior_ptid (int pid) | |
c906108c | 87 | |
c5aa993b | 88 | DESCRIPTION |
c906108c | 89 | |
39f77062 | 90 | These two functions act in unison to restore inferior_ptid in |
c5aa993b | 91 | case of an error. |
c906108c | 92 | |
c5aa993b | 93 | NOTES |
c906108c | 94 | |
39f77062 | 95 | inferior_ptid is a global variable that needs to be changed by many of |
c5aa993b | 96 | these routines before calling functions in procfs.c. In order to |
39f77062 KB |
97 | guarantee that inferior_ptid gets restored (in case of errors), you |
98 | need to call save_inferior_ptid before changing it. At the end of the | |
c5aa993b | 99 | function, you should invoke do_cleanups to restore it. |
