+ * This header file defines a set of POSIX errno values
+ * that fits consistently into the Mach error code "space" -
+ * i.e. these error code values can be mixed with kern_return_t's
+ * and mach_msg_return_t's and such without conflict.
+ * Higher-level services are not required to use these values
+ * (or, for that matter, any of the mach/sa header files),
+ * but if they use other values of their own choosing,
+ * those values may conflict with values in the Mach error code space,
+ * making it necessary to keep the different types of error codes separate.
+ *
+ * (For example, Lites uses BSD's errno values,
+ * which conflict with Mach's kern_return_t values,
+ * and therefore must carefully distinguish between BSD and Mach error codes
+ * and never return one type when the other is expected, etc. -
+ * we've found this to be a frequent source of bugs.)
+ *
+ * One (probably the main) disadvantage of using these error codes
+ * is that, since they don't start from around 0 like typical Unix errno values,
+ * it's impossible to provide a conventional Unix-style sys_errlist table for them.
+ * However, they are compatible with the POSIX-blessed strerror and perror routines.
