get_backwards_compatibility_lua_table()

WS_DLL_PUBLIC const GArray * get_backwards_compatibility_lua_table

(

void

)

Retrieve the table of backwards compatibility Lua names.

Returns a GArray of backwards_compatibiliity_lua_name entries.

Returns

Pointer to GArray of compatibility mappings.

wtap_dump_params_generate_idb()

wtap_block_t wtap_dump_params_generate_idb

(

const wtap_dump_params *

params

)

Generate an IDB, given a set of dump parameters, using the parameters' encapsulation type, snapshot length, and time stamp resolution. For use when a dump file has a given encapsulation type, and the source is not passing IDBs.

Note

This requires that the encapsulation type and time stamp resolution not be per-packet; it will terminate the process if either of them are.

Parameters

params

The wtap dump parameters.

Returns

A newly allocated IDB block.

wtap_file_get_nrb_for_new_file()

GArray * wtap_file_get_nrb_for_new_file

(

wtap *

wth

)

Gets new name resolution info for new file, based on existing info.

Creates a new wtap_block_t of name resolution info and only copies appropriate members for a new file.

Note

Use wtap_free_nrb() to free the returned pointer.

Parameters

wth	The wiretap session.

Returns

The new name resolution info, which must be freed.

wtap_file_get_shb_for_new_file()

GArray * wtap_file_get_shb_for_new_file

(

wtap *

wth

)

Gets new section header block for new file, based on existing info.

Creates a new wtap_block_t section header block and only copies appropriate members of the SHB for a new file. In particular, the comment string is copied, and any custom options which should be copied are copied. The os, hardware, and application strings are not copied.

Note

Use wtap_free_shb() to free the returned section header.

Parameters

wth	The wiretap session.

Returns

The new section header, which must be wtap_free_shb'd.

wtap_init_file_type_extensions()

void wtap_init_file_type_extensions	(	const struct file_extension_info *	file_extensions,
		unsigned	num_extensions
	)

Initialize the extensions array.

Parameters

file_extensions	Array of file extension info structures
num_extensions	Number of extensions in the array

wtap_init_file_type_subtypes()

void wtap_init_file_type_subtypes

(

const char *

app_env_var_prefix

)

Initialize file type subtypes for wiretap.

Parameters

app_env_var_prefix

The prefix for the application to determine what pcapNG behavior to use
