|THREAD-KEYRING(7)||Linux Programmer's Manual||THREAD-KEYRING(7)|
NAME¶thread-keyring - per-thread keyring
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) _tid.
A special serial number value, KEY_SPEC_THREAD_KEYRING, is defined that can be used in lieu of the actual serial number of the calling thread's thread keyring.
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 ENOKEY.
