Function Documentation

libwifi_add_tag()

int libwifi_add_tag	(	struct libwifi_tagged_parameters *	tagged_parameters,
		struct libwifi_tagged_parameter *	tagged_parameter
	)

Add a tagged parameter to a list of frame tagged parameters.

Parameters

tagged_parameters	A management frame's tagged parameters
tagged_parameter	The new tagged parameter

Definition at line 25 of file tag.c.

libwifi_check_tag()

int libwifi_check_tag	(	struct libwifi_tagged_parameters *	tags,
		int	tag_number
	)

Check if a tagged parameter is present via tag number.

Parameters

tags	A tagged parameters list
tag_number	The number of the tagged parameter to find

Returns

The number of times the supplied tag_number was found in tags

Definition at line 133 of file tag.c.

libwifi_create_tag()

size_t libwifi_create_tag	(	struct libwifi_tagged_parameter *	tagged_parameter,
		int	tag_number,
		const unsigned char *	tag_data,
		size_t	tag_length
	)

Create a tagged parameter from a tag number, length and data.

This can be useful when generating tags on their own, for use with action frame body's.

Parameters

tagged_parameter	A new tagged parameter struct
tag_number	Tagged parameter number
tag_data	The tag body
tag_length	Length of the tag body

Returns

length of the created tag

Definition at line 81 of file tag.c.

libwifi_dump_tag()

size_t libwifi_dump_tag	(	struct libwifi_tagged_parameter *	tag,
		unsigned char *	buf,
		size_t	buf_len
	)

Dump a tagged parameter into a raw buffer, for use with other buffers or injection.

Parameters

tag	A used tagged parameter struct
buf	A buffer for the raw data
buf_len	Length of buf

Definition at line 103 of file tag.c.

libwifi_free_tag()

void libwifi_free_tag

(

struct libwifi_tagged_parameter *

tagged_parameter

)

Free a tagged parameters body.

Parameters

tagged_parameter

A used tagged parameter

Definition at line 99 of file tag.c.

libwifi_get_tag_name()

char * libwifi_get_tag_name

(

int

tag_number

)

Get the name of a tagged parameter via a supplied tag number.

Parameters

tag_number

The number of the tagged parameter to name

Returns

Definition at line 149 of file tag.c.

libwifi_quick_add_tag()

int libwifi_quick_add_tag	(	struct libwifi_tagged_parameters *	tagged_parameters,
		int	tag_number,
		const unsigned char *	tag_data,
		size_t	tag_length
	)

Add a tagged parameter via tag number and data to a management frame.

Parameters

tagged_parameters	A management frame's tagged parameters
tag_number	Tagged parameter to add
tag_data	Data to copy into new tag
tag_length	Length of the new tag

Returns

0 on success, negative number on error

Definition at line 118 of file tag.c.

libwifi_remove_tag()

int libwifi_remove_tag	(	struct libwifi_tagged_parameters *	tagged_parameters,
		int	tag_number
	)

Remove a tagged parameter from a list of frame tagged parameters.

Parameters

tagged_parameters	A management frame's tagged parameters
tag_number	Number of the tag to remove

Definition at line 55 of file tag.c.
