KEYCTL_INVALIDATE(3)   Linux Key Management Calls   KEYCTL_INVALIDATE(3)

NAME         top

       keyctl_invalidate - invalidate a key

SYNOPSIS         top

       #include <keyutils.h>

       long keyctl_invalidate(key_serial_t key);

DESCRIPTION         top

       keyctl_invalidate() invalidates a key.  The key is scheduled for
       immediate removal from all the keyrings that point to it, after
       which it will be deleted.  The key will be ignored by all
       searches once this function is called even if it is not yet fully
       dealt with.

       The caller must have search permission on a key to be able to
       invalidate it.

RETURN VALUE         top

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

ERRORS         top
