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)). ATTRIBUTES
