NAME         top

       keyctl_move - Move a key between keyrings

SYNOPSIS         top

       #include <keyutils.h>

       long keyctl_move(key_serial_t key, key_serial_t from_keyring,
                        key_serial_t to_keyring, unsigned int flags);

DESCRIPTION         top

       keyctl_move() atomically unlinks key from from_keyring and links
       it into to_keyring in a single operation.  Depending on the flags
       set, a link to any matching key in to_keyring may get displaced.

       flags is a bitwise-OR of zero or more of the following flags:

              If there's a matching key in to_keyring, don't displace it
              but rather return an error.

       The caller must have write permission on both keyring to be able
       to create or remove links in them.

       The caller must have link permission on a key to be able to
       create a new link to it.
