yencodeStep

fnsize_t yencodeStep(ubyte[] inbuf, ref ubyte[] outbuf, ref int state, ref uint pcrc, ref uint crc)

Performs an yEncode 'encode step' on a chunk of raw data of length inlen pointed to by inbuf and writes to outbuf.

state should be initialized to #GMIME_YENCODE_STATE_INIT before beginning making the first call to this function. Subsequent calls should reuse state.

Along the same lines, pcrc and crc should be initialized to #GMIME_YENCODE_CRC_INIT before using.

Parameters

`inbuf`	input buffer
`outbuf`	output buffer
`state`	yencode state
`pcrc`	part crc state
`crc`	crc state

Returns

the number of bytes encoded.
