KEYCTL_REVOKE(2const)                               KEYCTL_REVOKE(2const)

NAME         top

       KEYCTL_REVOKE - revoke a key

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #include <linux/keyctl.h>  /* Definition of KEY* constants */
       #include <sys/syscall.h>   /* Definition of SYS_* constants */
       #include <unistd.h>

       long syscall(SYS_keyctl, KEYCTL_REVOKE, key_serial_t key);

DESCRIPTION         top

       Revoke the key with the ID provided in key.  The key is scheduled
       for garbage collection; it will no longer be findable, and will be
       unavailable for further operations.  Further attempts to use the
       key will fail with the error EKEYREVOKED.

       The caller must have write or setattr permission on the key.

RETURN VALUE         top

       On success, 0 is returned.

       On error, -1 is returned, and errno is set to indicate the error.

VERSIONS         top

       A wrapper is provided in the libkeyutils library:
       keyctl_revoke(3).

STANDARDS         top

       Linux.

HISTORY         top

       Linux 2.6.10.
