KEYCTL_REVOKE(3) Linux Key Management Calls KEYCTL_REVOKE(3)
keyctl_revoke - revoke a key
#include <keyutils.h> long keyctl_revoke(key_serial_t key);
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.
On success keyctl_revoke() returns 0. On error, the value -1 will be returned and errno will have been set to an appropriate error.
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 EKEYREVOKED The key has already been revoked.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.
This is a library function that can be found in libkeyutils. When linking, -lkeyutils should be specified to the linker.
