Public Methods

Decoder

inline

inline Decoder(int buffersize)

Parameters

• buffersize Internal read buffer size in bytes.

decode

inline

inline ssize_t decode(char value_in)

Decodes a single Base64 character to its 6-bit value.

Parameters

• value_in Base64 character.

Returns

Decoded 6-bit value, or a negative sentinel on invalid input.

decode

virtual inline

virtual inline ssize_t decode(const char * inbuf, size_t nread, char * outbuf)

Decodes a raw Base64 buffer into binary data.

Parameters

• inbuf Input Base64 characters.

• nread Number of characters to decode.

• outbuf Output buffer; must be at least nread * 3 / 4 bytes.

Returns

Number of binary bytes written.

decode

inline

inline void decode(std::istream & istrm, std::ostream & ostrm)

Decodes the entire input stream and writes binary output to ostrm. Resets the decoder state after completion.

Parameters

• istrm Source stream of Base64 data.

• ostrm Destination stream for decoded binary output.
