The door_revoke() function revokes access to a door descriptor. Door descriptors are created with door_create(3DOOR). The door_revoke() function performs an implicit call to close(2), marking the door descriptor d as invalid.

A door descriptor can only be revoked 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.

EPERM

The door descriptor was not created by this process (with door_create(3DOOR)).
