-.TH thread-keyring 7 2023-10-31 "Linux man-pages 6.7"
-.SH NAME
-thread-keyring \- per-thread keyring
-.SH DESCRIPTION
-The thread keyring is a keyring used to anchor keys on behalf of a process.
-It is created only when a thread requests it.
-The thread keyring has the name (description)
-.IR _tid .
-.P
-A special serial number value,
-.BR KEY_SPEC_THREAD_KEYRING ,
-is defined that can be used in lieu of the actual serial number of
-the calling thread's thread keyring.
-.P
-From the
-.BR keyctl (1)
-utility, '\fB@t\fP' can be used instead of a numeric key ID in
-much the same way, but as
-.BR keyctl (1)
-is a program run after forking, this is of no utility.
-.P
-Thread keyrings are not inherited across
-.BR clone (2)
-and
-.BR fork (2)
-and are cleared by
-.BR execve (2).
-A thread keyring is destroyed when the thread that refers to it terminates.
-.P
-Initially, a thread does not have a thread keyring.
-If a thread doesn't have a thread keyring when it is accessed,
-then it will be created if it is to be modified;
-otherwise the operation fails with the error
-.BR ENOKEY .
