Sigh. 40 * [92/02/16 14:14:38 jsb] 41 * 42 * Defined more robust xmm_decl. 43 * [92/02/09 12:55:40 jsb] 44 * 45 * Revision 2.4.2.1 92/01/21 21:54:33 jsb 46 * Moved IKOT_XMM_* definitions to kern/ipc_kobject.h. 47 * [92/01/21 18:21:45 jsb] 48 * 49 * De-linted. Supports new (dlb) memory object routines. 50 * Supports arbitrary reply ports to lock_request, etc. 51 * Converted mach_port_t (and port_t) to ipc_port_t. 52 * Added XMM_USE_MACROS conditional, off by default, 53 * which toggles between macros and functions for invocation 54 * routines. (Right now only the functions are provided.) 55 * [92/01/20 17:27:35 jsb] 56 * 57 * Revision 2.4 91/07/01 08:26:25 jsb 58 * Removed malloc, free definitions. 59 * Added xmm_decl macro. 60 * Renamed Xobj_allocate to xmm_obj_allocate. 61 * Added zone element to xmm_class structure. 62 * [91/06/29 14:41:25 jsb] 63 * 64 * Revision 2.3 91/06/18 20:53:00 jsb 65 * Removed bogus include. 66 * [91/06/18 19:06:29 jsb] 67 * 68 * Revision 2.2 91/06/17 15:48:28 jsb 69 * First checkin. 70 * [91/06/17 11:03:46 jsb] 71 * 72 */ 73 /* 74 * File: norma/xmm_obj.h 75 * Author: Joseph S.
