door_revoke(3DOOR)                                            Door Library Functions                                            door_revoke(3DOOR)

NAME

       door_revoke - revoke access to a door descriptor

SYNOPSIS

       cc -mt [ flag ... ] file ... -ldoor  [ 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(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() invoca-
       tion 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(3DOOR)).
