56function obtains a list of character encodings that are supported by the
57.Xr iconv 3
58call.
59The

61callback function will be called, where the
62.Fa count
63argument will be set to the number of the encoding names found, the
64.Fa names
65argument will be the list of the supported encoding names and the
66.Fa arg
67argument will be the \"outer\"
68.Fa arg
69argument of the
70.Fn iconvlist
71function.
72This argument can be used to interchange custom data between the caller of
73.Fn iconvlist
74and the callback function.
75.Pp
76If an error occurs,
77.Fa names
78will be NULL when calling
79.Fn do_one .
