Синопсис (Synopsis)
#include <linux/keyctl.h> /* Definition of KEY* constants */
#include <sys/syscall.h> /* Definition of SYS_* constants */
#include <unistd.h>
long syscall(SYS_keyctl, int operation, unsigned long arg2,
unsigned long arg3, unsigned long arg4,
unsigned long arg5);
Note: glibc provides no wrapper for keyctl(), necessitating the
use of syscall(2).
