BloombergLP::bdlde::QuotedPrintableEncoder::endConvert

Terminate encoding for this encoder; write any retained output (e.g., from a previous call to convert with a non‐zero maxNumOut argument) 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 specified numOut the number of output bytes produced. Return a non‐negative value on success and a negative value otherwise. A successful return status indicates the number of characters that would be output if endConvert were called subsequently with no output limit. 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 reset; once this method returns a zero status, a subsequent call will place this encoder in the error state, and return an error status.
