NAME

       keyctl_revoke - revoke a key

SYNOPSIS

       #include <keyutils.h>

       long keyctl_revoke(key_serial_t key);

DESCRIPTION

       keyctl_revoke() marks a key as being revoked.

       After this operation has been performed on a key, attempts to
       access it will meet with error EKEYREVOKED.

       The caller must have write permission on a key to be able to
       revoke it.

RETURN VALUE

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

ERRORS

       ENOKEY The specified key does not exist.

       EKEYREVOKED
              The key has already been revoked.

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

LINKING

       This is a library function that can be found in libkeyutils.
