tlv8_data_t *	tlv_find_tlv8 (const uint8_t *message, uint32_t message_length, uint8_t type)

Detailed Description

Functions to read/write Type-Length-Value (TLV) data used in many common protocols.

Function Documentation

tlv16_data_t* tlv_find_tlv16	(	const uint8_t *	message,
		uint32_t	message_length,
		uint16_t	type
	)

Finds a particular type from a buffer of TLV data.

Returns a pointer to the first TLV which has a type that matches the given type. The pointer points to the 'type' field. This is the 16-bit-Type & 16-bit-Lenght version

Parameters

[in]	message	: A pointer to the source TLV data to be searched
[in]	message_length	: The length of the source TLV data to be searched
[in]	type	: The TLV type to search for

Returns: Pointer to start of first matching TLV, or NULL if not found

tlv8_data_t* tlv_find_tlv8	(	const uint8_t *	message,
		uint32_t	message_length,
		uint8_t	type
	)

Finds a particular type from a buffer of TLV data.

Returns a pointer to the first TLV which has a type that matches the given type. The pointer points to the 'type' field. This is the 8-bit-Type & 8-bit-Lenght version

Parameters

[in]	message	: A pointer to the source TLV data to be searched
[in]	message_length	: The length of the source TLV data to be searched
[in]	type	: The TLV type to search for

Returns: Pointer to start of first matching TLV, or NULL if not found
