NAME

door_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() 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.

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)).
