Instead, they should access 65its functions using the architecture-dependent 66library. 67.Pp 68.Sh RETURN VALUES 69See the manual pages for specific architecture-dependent function calls 70for information about their return values. 71.Sh HISTORY 72The 73.Fn sysarch 74function call appeared in 75NetBSD 0.9a. 76
