19 * Temporarily changes to the given uid. If the effective user id is not
20 * root, this does nothing. This call cannot be nested.
22 void temporarily_use_uid(uid_t uid);
25 * Restores the original effective user id after temporarily_use_uid().
26 * This should only be called while temporarily_use_uid is effective.
28 void restore_uid(void);
31 * Permanently sets all uids to the given uid. This cannot be called while
32 * temporarily_use_uid is effective. This must also clear any saved uids.
