pub fn set_thread_res_uid(ruid: Uid, euid: Uid, suid: Uid) -> Result<()>Expand description
setresuid(ruid, euid, suid)
§Warning
This is not the setresxid you are looking for… POSIX requires xids to be process granular, but on Linux they are per-thread. Thus, this call only changes the xid for the current thread, not the entire process even though that is in violation of the POSIX standard.
For details on this distinction, see the C library vs. kernel differences
in the manual page and the notes in set_thread_uid. This
call implements the kernel behavior.
