+.Sh NAME
+.Nm sysarch
+.Nd architecture-dependent system call
+.Sh SYNOPSIS
+.Fd #include <machine/sysarch.h>
+.Ft int
+.Fn sysarch "int number" "void *args"
+.Sh DESCRIPTION
+.Fn Sysarch
+performs the architecture-dependent function
+specified by
+.Fa number
+with the arguments specified by the
+.Fa args
+pointer.
+.Fa Args
+is a pointer to a structure defining the actual
+arguments of the function.
+Symbolic constants and argument structures
+for the architecture-dependent
+functions can be found in the header file
+.Ao Pa machine/sysarch.h Ac .
+.Pp
+The
+.Fn sysarch
+system call should never be called directly by
+user programs.  Instead, they should access
+its functions using the architecture-dependent
+library.
+.Pp
+.Sh RETURN VALUES
+See the manual pages for specific architecture-dependent function calls
+for information about their return values.
