BloombergLP::bdlde::Base64Encoder::endConvert

Terminate encoding for this encoder; write any retained output (e.g., from a previous call to convert) to the specified out buffer. Optionally specify the maxNumOut 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 if output was successfully completed and a non‐zero 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 encoder in the error state, and return an error status.
