Complete decoding and flush retained output to `out` with limits.

== Synopsis

Declared in `<bdlde_base64decoder.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class OUTPUT_ITERATOR>
int
endConvert(
    OUTPUT_ITERATOR out,
    int* numOut,
    int maxNumOut = ‐1);
----

== Description

Terminate decoding for this decoder; write any retained output to the specified `out` buffer. The argument `maxNumOut` is the limit on the number of bytes to output; if `maxNumOut` is negative, no limit is imposed. Load into the (optionally) specified `numOut` the number of output bytes produced. Return 0 on success, a positive number of retained bytes if the output limit was reached, and a negative value otherwise. See the preceding overload for full contract details.

== Return Value

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