Function Documentation

dvb_add_chartbl()

WS_DLL_PUBLIC void dvb_add_chartbl	(	proto_tree *	tree,
		int	hf,
		tvbuff_t *	tvb,
		int	offset,
		int	length,
		dvb_encoding_e	encoding
	)

Adds a character table to the protocol tree.

This function adds a character table to the protocol tree based on the provided parameters.

Parameters

tree	The protocol tree to which the character table will be added.
hf	The field ID for the character table.
tvb	The TV buffer containing the data.
offset	The offset within the TV buffer where the data starts.
length	The length of the data in the TV buffer.
encoding	The encoding type of the character table.

dvb_analyze_string_charset()

WS_DLL_PUBLIC unsigned dvb_analyze_string_charset	(	tvbuff_t *	tvb,
		int	offset,
		int	length,
		dvb_encoding_e *	encoding
	)

Analyzes the character set of a DVB string.

Determines the encoding of a DVB string based on its first byte and length.

Parameters

tvb	The TVB buffer containing the DVB data.
offset	The starting offset within the TVB buffer.
length	The length of the DVB string to analyze.
encoding	Pointer to store the detected encoding.

Returns

Number of bytes processed or 1 if invalid.

WS_DLL_PUBLIC unsigned dvb_enc_to_item_enc

(

dvb_encoding_e

encoding

)

Convert DVB encoding to item encoding.

Parameters

encoding

The DVB encoding to convert.

Returns

The corresponding item encoding.
