It will work the same as PORT_TYPE_ALL in this case. * * Revision 2.10 89/03/09 20:22:30 rpd * More cleanup. * * Revision 2.9 89/03/05 16:49:06 rpd * Moved ownership rights under MACH_IPC_XXXHACK. * [89/02/16 rpd] * * Revision 2.8 89/02/25 18:39:37 gm0w * Changes for cleanup. * * Revision 2.7 89/02/07 00:52:59 mwyoung * Relocated from sys/port.h * * Revision 2.6 89/01/10 23:32:30 rpd * Only define PORT_ENABLED when MACH_IPC_XXXHACK is turned on. * [89/01/10 23:10:59 rpd] * * Revision 2.5 88/09/25 22:16:30 rpd * Removed PORT_INVALID. Cast PORT_NULL as port_name_t and * PORT_ENABLED as port_set_name_t. * [88/09/24 18:11:43 rpd] * * Revision 2.4 88/07/29 03:21:36 rpd * When non-KERNEL, don't define PORT_ILLEGAL and define PORT_ENABLED as * a global port-set variable. Compatibility code in libmach will implement * port_enable/port_disable using a PORT_ENABLED variable. * * Revision 2.3 88/07/20 21:06:54 rpd * Added port_set_name_t, port_name_array_t, port_type_t, port_type_array_t. * Added PORT_TYPE_* definitions. * Add port_name_t type. * * Revision 2.2 88/07/17 18:53:32 mwyoung * . * * Revision 2.1.2.1 88/06/28 20:51:47 mwyoung * Pick up rpd's changes. * * Revision 2.1.1.1 88/06/23 23:30:39 rpd * Add port_name_t type. * * 10-Nov-86 Michael Young (mwyoung) at Carnegie-Mellon University * Added PORT_INVALID and some more documentation. * * 28-Oct-86 Michael Young (mwyoung) at Carnegie-Mellon University * Added port_*_t types; not all are used by the * kernel, but names are exported for consistency. * * 21-Oct-86 Michael Young (mwyoung) at Carnegie-Mellon University * Added port_rcv_t type; used by the interface generator. * * 19-Jul-86 Michael Young (mwyoung) at Carnegie-Mellon University * Documentation change only. * * 26-Jun-86 Michael Young (mwyoung) at Carnegie-Mellon University * Added PORT_ENABLED to refer to any enabled port. * * 8-May-86 Michael Young (mwyoung) at Carnegie-Mellon University * Created * */ /* * File: mach/port.h * * Definition of a port * * [The basic port_t type should probably be machine-dependent, * as it must be represented by a 32-bit integer.] */ #ifndef _MACH_PORT_H_ #define _MACH_PORT_H_ typedef int port_name_t; /* A capability's name */ typedef port_name_t port_set_name_t; /* Descriptive alias */ typedef port_name_t *port_name_array_t; typedef int port_type_t; /* What kind of capability? */ typedef port_type_t *port_type_array_t; /* Values for port_type_t */ #define PORT_TYPE_NONE 0 /* No rights */ #define PORT_TYPE_SEND 1 /* Send rights */ #define PORT_TYPE_RECEIVE_OWN 7 /* Send, receive, ownership */ #define PORT_TYPE_SET 9 /* Set ownership */ #define PORT_TYPE_LAST 10 /* Last assigned */ typedef port_name_t port_t; /* Port with send rights */ typedef port_t port_all_t; /* Port with receive and ownership */ typedef port_t *port_array_t; #define PORT_NULL ((port_name_t) 0) /* Used to denote no port; legal value */ #define PORT_BACKLOG_DEFAULT 5 #define PORT_BACKLOG_MAX 16 #endif
