27.Os
28.Sh NAME
29.Nm sysdecode_sockopt_name
30.Nd lookup name of socket option
31.Sh LIBRARY
32.Lb libsysdecode
33.Sh SYNOPSIS
34.In sysdecode.h
35.Ft const char *
36.Fn sysdecode_sockopt_name "int level" "int optname"
37.Sh DESCRIPTION
38The
39.Fn sysdecode_sockopt_name
40function returns a text description of the socket option name passed in the
41.Fa optname
42argument to
43.Xr getsockopt 2 .
44.Fn sysdecode_sockopt_name
45takes the socket option
46.Fa level
47as well as the option name to uniquely identify the option.
48.Sh SEE ALSO
49.Xr sysdecode_sockopt_level 3
50.Sh BUGS
51Socket option levels and names are protocol-specific.
52Both
53.Fn sysdecode_sockopt_level
54and
55.Fn sysdecode_sockopt_name
56should possibly accept the protocol family as an additional argument.
