keyctl_*() − key management function wrappers
The keyctl() system call is a multiplexor for a number of key management functions. These should be called via the wrappers in the libkeyutils library.
The functions can be compiled in by including the keyutils header file:
#include <keyutils.h>
and then telling the linker it should link in the library:
