+.Sh SYNOPSIS
+.In iconv.h
+.Ft void
+.Fo iconvlist "char ***names" "size_t count" "bool paired"
+.Fa "int \*[lp]*do_one\*[rp]\*[lp]unsigned int *count, const char * const *names, void *arg\*[rp]"
+.Fa "void *arg"
+.Fc
+.Sh DESCRIPTION
+The
+.Fn iconvlist
+function obtains a list of character encodings that are supported by the
+.Xr iconv 3
+call.
+The
+.Fn do_one
+callback function will be called, where the
+.Fa count
+argument will be set to the number of the encoding names found, the
+.Fa names
+argument will be the list of the supported encoding names and the
+.Fa arg
+argument will be the \"outer\"
+.Fa arg
+argument of the
+.Fn iconvlist
+function.
+This argument can be used to interchange custom data between the caller of
+.Fn iconvlist
+and the callback function.
+.Pp
+If an error occurs,
+.Fa names
+will be NULL when calling
+.Fn do_one .
