-.SH NAME
-process-keyring \- per-process shared keyring
-.SH DESCRIPTION
-The process keyring is a keyring used to anchor keys on behalf of a process.
-It is created only when a process requests it.
-The process keyring has the name (description)
-.IR _pid .
-.P
-A special serial number value,
-.BR KEY_SPEC_PROCESS_KEYRING ,
-is defined that can be used in lieu of the actual serial number of
-the calling process's process keyring.
-.P
-From the
-.BR keyctl (1)
-utility, '\fB@p\fP' can be used instead of a numeric key ID in
-much the same way, but since
-.BR keyctl (1)
-is a program run after forking, this is of no utility.
-.P
-A thread created using the
-.BR clone (2)
-.B CLONE_THREAD
-flag has the same process keyring as the caller of
-.BR clone (2).
-When a new process is created using
-.BR fork ()
-it initially has no process keyring.
-A process's process keyring is cleared on
-.BR execve (2).
-The process keyring is destroyed when the last
-thread that refers to it terminates.
-.P
-If a process doesn't have a process keyring when it is accessed,
-then the process keyring will be created if the keyring is to be modified;
-otherwise, the error
-.B ENOKEY
-results.
