BloombergLP::bdlde::Base64Decoder::endConvert

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. 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, the positive number of bytes still retained by this decoder if the maxNumOut 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.
