The
iconvlist()
function obtains a list of character encodings that are supported by the
iconv(3)
call.
The
do_one()
callback function will be called, where the
count
argument will be set to the number of the encoding names found, the
names
argument will be the list of the supported encoding names and the
arg
argument will be the
arg
argument of the
iconvlist()
function.
This argument can be used to interchange custom data between the caller of
iconvlist()
and the callback function.
If an error occurs,
names
will be NULL when calling
do_one().
