    NAME

    keyctl_link - Link a key to a keyring
    keyctl_unlink - Unlink a key from a keyring
    
     
    

    SYNOPSIS

    #include <keyutils.h>
    
    long keyctl_link(key_serial_t key, key_serial_t keyring);
    
    long keyctl_unlink(key_serial_t key, key_serial_t keyring);
    
     

    DESCRIPTION

    keyctl_link() creates a link from keyring to key, displacing any link to another key of the same type and description in that keyring if one exists. keyctl_unlink() removes the link from keyring to key if it exists. The caller must have write permission on a keyring to be able create or remove links in it. The caller must have link permission on a key to be able to create a link to it.  

    RETURN VALUE

    On success keyctl_link() and keyctl_unlink() 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 the keyring specified are invalid.
    EKEYEXPIRED
    The key or the keyring specified have expired.
    EKEYREVOKED
    The key or the keyring specified have been revoked.
    EACCES
    The keyring exists, but is not writable by the calling process. For keyctl_link() only:
    ENOMEM
    Insufficient memory to expand the keyring
    EDQUOT
    Expanding the keyring would exceed the keyring owner's quota.
    EACCES
    The key exists, but is not linkable by the calling process.
     

    LINKING

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