:relfileprefix: ../../../
:mrdocs:

Complete decoding and flush any retained output to `out`.

== Synopsis

Declared in `<bdlde_base64decoder.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class OUTPUT_ITERATOR>
int
endConvert(OUTPUT_ITERATOR out);
----

== Description

Terminate decoding for this decoder; write any retained output (e.g., from a previous call to `convert` with a non‐zero optionally specified `maxNumOut` argument) to the specified `out` buffer; encode any unprocessed input characters that do not complete a 3‐byte sequence. Return 0 on success, the positive number of bytes _still_ retained by this decoder if an output limit was reached, and a negative value otherwise. Any retained bytes are available on a subsequent call to `endConvert`. Once this method is called, no additional input may be supplied without an intervening call to `resetState`; once this method returns a zero status, a subsequent call will place this decoder in the error state, and return an error status.

== Return Value

0 on success, a positive number of retained bytes if an output limit was reached, and a negative value otherwise
