You can use this to see if the next call to readkey() is going to block or to simply wait for the user to…

keyctl_update – Update a key Synopsis#include <keyutils.h> long keyctl_update(key_serial_t key, const void *payload, size_t plen);Descriptionkeyctl_update() updates the payload of a key if the key type permits it. The caller must have write permission on a key to be able update it. payload and plen specify the data for the new payload. payload may be NULL…

keyctl_setperm – Change the permissions mask on a key Synopsis#include <keyutils.h> long keyctl_setperm(key_serial_t key, key_perm_t perm);Descriptionkeyctl_setperm() changes the permissions mask on a key. A process that does not have the SysAdmin capability may not change the permissions mask on a key that doesn’t have the same UID as the caller. The caller must have setattr…

keyctl_set_timeout – Set the expiration timer on a key Synopsis#include <keyutils.h> long keyctl_set_timeout(key_serial_t key, unsigned timeout);Descriptionkeyctl_set_timeout() sets the expiration timer on a key to timeout seconds into the future. Setting timeout to zero cancels the expiration, assuming the key hasn’t already expired. When the key expires, further attempts to access it will be met with…
