		fr_dbuff_t *	in,
		bool	add_padding,
		char const	alphabet[static SBUFF_CHAR_CLASS]
	)

Base 64 encode binary data.

Base64 encode in bytes to base64, writing to out.

Parameters

[out]	out	Where to write Base64 string.
[in]	in	Data to encode.
[in]	add_padding	Add padding bytes.
[in]	alphabet	to use for encoding.

Returns

• Amount of data we wrote to the buffer.
• <0 the number of bytes we would have needed in the ouput buffer.
