The door_revoke() function revokes access to a door descriptor. Door descriptors are created with door_create(3C). The door_revoke() function performs an implicit call to close(2), marking the door descriptor d as invalid.
A door descriptor can be revoked only by the process that created it. Door invocations that are in progress during a door_revoke() invocation are allowed to complete normally.
Upon successful completion, door_revoke() returns 0. Otherwise, door_revoke() returns -1 and sets errno to indicate the error.
The door_revoke() function will fail if: EBADF
An invalid door descriptor was passed.
The door descriptor was not created by this process (with door_create(3C)).
