NAME

       keyctl_invalidate - invalidate a key

SYNOPSIS

       #include <keyutils.h>

       long keyctl_invalidate(key_serial_t key);

DESCRIPTION

       keyctl_invalidate()  invalidates  a  key.  The key is scheduled for immediate removal from
       all the keyrings that point to it, after which it  will  be  deleted.   The  key  will  be
       ignored  by  all  searches  once this function is called even if it is not yet fully dealt
       with.

       The caller must have search permission on a key to be able to invalidate it.

RETURN VALUE

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

ERRORS

       ENOKEY The key specified is invalid.

       EKEYEXPIRED
              The key specified has expired.

       EKEYREVOKED
              The key specified had been revoked.

       EACCES The key exists, but is not searchable 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.
