манипулировать средствами управления ключами ядра (manipulate the kernel's key management facility)
Примечание (Note)
A wrapper is provided in the libkeyutils library. (The
accompanying package provides the <keyutils.h> header file.)
When employing the wrapper in that library, link with -lkeyutils.
However, rather than using this system call directly, you
probably want to use the various library functions mentioned in
the descriptions of individual operations above.
