|
|
The

|
|
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.

|
|
If an error occurs,
|
|
.Fa names
|
