Function rustix::thread::id::set_thread_res_gid
source · pub fn set_thread_res_gid(rgid: Gid, egid: Gid, sgid: Gid) -> Result<()>Expand description
setresgid(rgid, egid, sgid)
§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_gid. This
call implements the kernel behavior.
