Function Documentation

exp_pdu_open()

bool exp_pdu_open	(	exp_pdu_t *	data,
		char *	pathname,
		int	file_type_subtype,
		int	fd,
		const char *	comment,
		int *	err,
		char **	err_info
	)

Use the given file descriptor for writing an output file. Can only be called once and exp_pdu_pre_open() must be called before.

Parameters

[out]	err	Will be set to an error code on failure.
[out]	err_info	for some errors, a string giving more details of the error

Returns

true on success or false on failure.

exp_pdu_pre_open()

char * exp_pdu_pre_open	(	const char *	tap_name,
		const char *	filter,
		exp_pdu_t *	exp_pdu_tap_data
	)

Registers the tap listener which will add matching packets to the exported file. Must be called before exp_pdu_open.

Parameters

tap_name	One of the names registered with register_export_pdu_tap().
filter	An tap filter, may be NULL to disable filtering which improves performance if you do not need a filter.

Returns

NULL on success or an error string on failure which must be freed with g_free(). Failure could occur when the filter or tap_name are invalid.
