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- The key has already been revoked.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. When linking, -lkeyutils should be specified to the linker.
