Detailed Description

Column info.

Function Documentation

col_cleanup()

WS_DLL_PUBLIC void col_cleanup

(

column_info *

cinfo

)

Cleanup all the data structures for constructing column data; undoes the allocations that col_setup() does.

col_custom_get_filter()

WS_DLL_PUBLIC char * col_custom_get_filter	(	struct epan_dissect *	edt,
		column_info *	cinfo,
		const int	col
	)

Get a filter expression for a custom column. This string must be g_free'd.

col_data_changed()

WS_DLL_PUBLIC bool col_data_changed

(

void

)

Check to see if our column data has changed, e.g. we have new request/response info.

col_fill_in()

WS_DLL_PUBLIC void col_fill_in	(	packet_info *	pinfo,
		const bool	fill_col_exprs,
		const bool	fill_fd_colums
	)

Fill in all (non-custom) columns of the given packet.

col_fill_in_error()

WS_DLL_PUBLIC void col_fill_in_error	(	column_info *	cinfo,
		frame_data *	fdata,
		const bool	fill_col_exprs,
		const bool	fill_fd_colums
	)

Fill in columns if we got an error reading the packet. We set most columns to "???", and set the Info column to an error message.

col_fill_in_frame_data()

WS_DLL_PUBLIC void col_fill_in_frame_data	(	const frame_data *	fd,
		column_info *	cinfo,
		const int	col,
		bool const	fill_col_exprs
	)

Fill in all columns of the given packet which are based on values from frame_data.

col_init()

void col_init ( column_info *  cinfo, const struct epan_session *  epan  )

extern

Initialize the data structures for constructing column data.

col_setup()

WS_DLL_PUBLIC void col_setup	(	column_info *	cinfo,
		const int	num_cols
	)

Allocate all the data structures for constructing column data, given the number of columns.
