DOOR_REVOKE(3C)DOOR_REVOKE(3C)NAMEdoor_revoke - revoke access to a door descriptor
SYNOPSIS
cc -mt [ flag... ] file... [ library... ]
#include <door.h>
int door_revoke(int d);
DESCRIPTION
The door_revoke() function revokes access to a door descriptor. Door
descriptors are created with door_create(3C). The door_revoke() func‐
tion performs an implicit call to close(2), marking the door descrip‐
tor 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.
RETURN VALUES
Upon successful completion, door_revoke() returns 0. Otherwise,
door_revoke() returns −1 and sets errno to indicate the error.
ERRORS
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(3C)).
