| * (pre-GNU) HISTORY |
| * |
| * Revision 2.6 93/01/14 17:41:31 danner |
| * Standardized include symbol name. |
| * [92/06/10 pds] |
| * |
| * Revision 2.5 92/03/31 15:18:11 rpd |
| * Added err_bootstrap for bootstrap errors. |
| * [92/03/09 rpd] |
| * |
| * Revision 2.4 91/05/14 16:51:24 mrt |
| * Correcting copyright |
| * |
| * Revision 2.3 91/02/05 17:31:48 mrt |
| * Changed to new Mach copyright |
| * [91/02/01 17:16:50 mrt] |
| * |
| * Revision 2.2 90/06/02 14:57:47 rpd |
| * Added err_mach_ipc for new IPC. |
| * [90/03/26 22:28:42 rpd] |
| * |
| * Revision 2.1 89/08/03 16:02:07 rwd |
| * Created. |
| * |
| * Revision 2.4 89/02/25 18:13:18 gm0w |
| * Changes for cleanup. |
| * |
| * Revision 2.3 89/02/07 00:51:57 mwyoung |
| * Relocated from sys/error.h |
| * |
| * Revision 2.2 88/10/18 00:37:31 mwyoung |
| * Added {system,sub and code}_emask |
| * [88/10/17 17:06:58 mrt] |
| * |
| * Added {system,sub and code}_emask |
| * |
| * 12-May-88 Mary Thompson (mrt) at Carnegie Mellon |
| * Changed mach_error_t from unsigned int to kern_return_t |
| * which is a 32 bit integer regardless of machine type. |
| * unsigned int was incompatible with old usages of mach_error. |
| * |
| * 10-May-88 Douglas Orr (dorr) at Carnegie-Mellon University |
| * Missing endif replaced |
| * |
| * 5-May-88 Mary Thompson (mrt) at Carnegie Mellon |
| * Changed typedef of mach_error_t from long to unsigned int |
| * to keep our Camelot users happy. Also moved the nonkernel |
| * function declarations from here to mach_error.h. |
| * |
| * 10-Feb-88 Douglas Orr (dorr) at Carnegie-Mellon University |
| * Created. |
