guint32 camel_mime_filter_yenc_get_pcrc (CamelMimeFilterYenc *yenc);
Get the computed part crc or (guint32) -1 on fail.

Returns : |
the computed part crc or (guint32) -1 on fail.

guint32 camel_mime_filter_yenc_get_crc (CamelMimeFilterYenc *yenc);
Get the computed crc or (guint32) -1 on fail.

gsize camel_ydecode_step (const guchar *in,
gsize inlen,
guchar *out,
gint *state,
guint32 *pcrc,
guint32 *crc);
Performs a 'decode step' on a chunk of yEncoded data of length
inlen pointed to by in and writes to out. Assumes the =ybegin
and =ypart lines have already been stripped off.
To get the crc32 value of the part, use CAMEL_MIME_YENCODE_CRC_FINAL
(pcrc). If there are more parts, you should reuse crc without
re-initializing. Once all parts have been decoded, you may get the
combined crc32 value of all the parts using CAMEL_MIME_YENCODE_CRC_FINAL
(crc).

gsize camel_yencode_step (const guchar *in,
gsize inlen,
guchar *out,
gint *state,
guint32 *pcrc,
guint32 *crc);
Performs an yEncode 'encode step' on a chunk of raw data of length
inlen pointed to by in and writes to out.
state should be initialized to CAMEL_MIME_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
CAMEL_MIME_YENCODE_CRC_INIT before using.

gsize camel_yencode_close (const guchar *in,
gsize inlen,
guchar *out,
gint *state,
guint32 *pcrc,
guint32 *crc);
Call this function when finished encoding data with camel_yencode_step to flush off the remaining state.
CAMEL_MIME_YENCODE_CRC_FINAL (pcrc) will give you the crc32 of the
encoded "part". If there are more "parts" to encode, you should
re-use crc when encoding the next "parts" and then use
CAMEL_MIME_YENCODE_CRC_FINAL (crc) to get the combined crc32 value of
all the parts.
