31.Dt SYSARCH 2
32.Os
33.Sh NAME
34.Nm sysarch
35.Nd architecture-dependent system call
36.Sh LIBRARY
37.Lb libc
38.Sh SYNOPSIS
39.In machine/sysarch.h
40.Ft int
41.Fn sysarch "int number" "void *args"
42.Sh DESCRIPTION
43The
44.Fn sysarch
45system call
46performs the architecture-dependent function
47specified by
48.Fa number
49with the arguments specified by the
50.Fa args
51pointer.
52The
53.Fa args
54argument
55is a pointer to a structure defining the actual
56arguments of the function.
57Symbolic constants and argument structures
58for the architecture-dependent
59functions can be found in the header file
60.In machine/sysarch.h .
61.Pp
62The
63.Fn sysarch
64system call should never be called directly by
65user programs.
66Instead, they should access
67its functions using the architecture-dependent
68library.
69.Sh RETURN VALUES
70See the manual pages for specific architecture-dependent system calls
71for information about their return values.
