NAME

       keyctl_move - Move a key between keyrings

SYNOPSIS

       #include <keyutils.h>

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

DESCRIPTION

       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:

       KEYCTL_MOVE_EXCL
              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 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.

RETURN VALUE

       On success keyctl_move() return 0.  On error, the value -1 will be returned and errno will have been  set
       to an appropriate error.

ERRORS

       ENOKEY The key or one of the keyrings specified are invalid.

       ENOKEY A key with the same type and description is present in to_keyring and KEYCTL_MOVE_EXCL is set.

       EKEYEXPIRED
              The key or one of the keyrings specified have expired.

       EKEYREVOKED
              The key or one of the keyrings specified have been revoked.

       EACCES The key exists, but is not linkable by the calling process.

       EACCES The keyrings exist, but are not writable by the calling process.

       ENOMEM Insufficient memory to effect the changes.

       EDQUOT Expanding to_keyring would exceed the keyring owner's quota.

LINKING

       This  is  a  library  function  that  can  be  found  in libkeyutils.  When linking, -lkeyutils should be
       specified to the linker.
