KEYCTL(3) Linux Key Management Calls KEYCTL(3)
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:
-lkeyutils
