Member Data Documentation

◆ contiguous_len

guint32 _fragment_head::contiguous_len

contiguous length from head up to first gap

◆ datalen

guint32 _fragment_head::datalen

When flags&FD_BLOCKSEQUENCE is set, the index of the last block (segments in datagram + 1); otherwise the number of bytes of the full datagram. Only valid in the first item of the fragments list when flags&FD_DATALEN is set.

◆ error

const char* _fragment_head::error

Null if the reassembly had no error; non-null if it had an error, in which case it's the string for the error.

◆ first_gap

struct _fragment_item* _fragment_head::first_gap

pointer to last fragment before first gap. NULL if there is no fragment starting at offset 0

◆ flags

guint32 _fragment_head::flags

XXX - do some of these apply only to reassembly heads and others only to fragments within a reassembly?

◆ fragment_nr_offset

guint32 _fragment_head::fragment_nr_offset

offset for frame numbering, for sequences, where the provided fragment number of the first fragment does not start with 0

◆ frame

guint32 _fragment_head::frame

maximum of all frame numbers added to reassembly

◆ len

guint32 _fragment_head::len

When flags&FD_BLOCKSEQUENCE and FD_DEFRAGMENTED are set, the number of bytes of the full datagram. Otherwise not valid.

◆ reas_in_layer_num

guint8 _fragment_head::reas_in_layer_num

The current "depth" or layer number in the current frame where reassembly was completed. Example: in SCTP there can be several data chunks and we want the reassembled tvb for the final segment only.

◆ reassembled_in

guint32 _fragment_head::reassembled_in

frame where this PDU was reassembled, only valid when FD_DEFRAGMENTED is set

◆ ref_count

guint _fragment_head::ref_count

reference count in reassembled_table
