keyctl_revoke - revoke a key
#include <keyutils.h>

it will meet with error EKEYREVOKED.
The caller must have write permission on a key to be able revoke it.
On success keyctl_revoke() returns 0. On error, the value -1 will be
returned and errno will have been set to an appropriate error.

EKEYREVOKED
The key has already been revoked.
EACCES The named key exists, but is not writable by the calling
process.
This is a library function that can be found in libkeyutils. When
linking, -lkeyutils should be specified to the linker.
