61 *
62 * Added {system,sub and code}_emask
63 *
64 * 12-May-88 Mary Thompson (mrt) at Carnegie Mellon
65 * Changed mach_error_t from unsigned int to kern_return_t
66 * which is a 32 bit integer regardless of machine type.
67 * unsigned int was incompatible with old usages of mach_error.
68 *
69 * 10-May-88 Douglas Orr (dorr) at Carnegie-Mellon University
70 * Missing endif replaced
71 *
72 * 5-May-88 Mary Thompson (mrt) at Carnegie Mellon
73 * Changed typedef of mach_error_t from long to unsigned int
74 * to keep our Camelot users happy. Also moved the nonkernel
75 * function declarations from here to mach_error.h.
76 *
77 * 10-Feb-88 Douglas Orr (dorr) at Carnegie-Mellon University
78 * Created.
