41.Sh NAME
42.Nm sysarch
43.Nd architecture-dependent system call
44.Sh LIBRARY
45.Lb libc
46.Sh SYNOPSIS
47.In machine/sysarch.h
48.Ft int
49.Fn sysarch "int number" "void *args"
50.Sh DESCRIPTION
51.Fn Sysarch
52performs the architecture-dependent function
53specified by
54.Fa number
55with the arguments specified by the
56.Fa args
57pointer.
58.Fa Args
59is a pointer to a structure defining the actual
60arguments of the function.
61Symbolic constants and argument structures
62for the architecture-dependent
63functions can be found in the header file
44cb301e 64.In machine/sysarch.h .

65.Pp
66The
67.Fn sysarch
68system call should never be called directly by
69user programs. Instead, they should access
70its functions using the architecture-dependent
71library.
72.Sh RETURN VALUES
73See the manual pages for specific architecture-dependent function calls
74for information about their return values.
