c5aa993b | 82 | SYNOPSIS |
c906108c | 83 | |
c5aa993b JM |
84 | struct cleanup *save_inferior_pid () |
85 | void restore_inferior_pid (int pid) | |
c906108c | 86 | |
c5aa993b | 87 | DESCRIPTION |
c906108c | 88 | |
c5aa993b JM |
89 | These two functions act in unison to restore inferior_pid in |
90 | case of an error. | |
c906108c | 91 | |
c5aa993b | 92 | NOTES |
c906108c | 93 | |
c5aa993b JM |
94 | inferior_pid is a global variable that needs to be changed by many of |
95 | these routines before calling functions in procfs.c. In order to | |
96 | guarantee that inferior_pid gets restored (in case of errors), you | |
97 | need to call save_inferior_pid before changing it. At the end of the | |
98 | function, you should invoke do_cleanups to restore it. | |
