Create a new CamelMimeFilterYenc filter object.

void camel_mime_filter_yenc_set_crc (CamelMimeFilterYenc *yenc, guint32 crc);
Sets the current crc32 value on the yEnc filter yenc
to crc

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

a CamelMimeFilterYenc object |
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.

size_t camel_ydecode_step (unsigned char *in, size_t inlen, unsigned char *out, int *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
).

size_t camel_yencode_step (unsigned char *in, size_t inlen, unsigned char *out, int *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.

size_t camel_yencode_close (unsigned char *in, size_t inlen, unsigned char *out, int *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.
