Function Documentation

nbnsCompareName()

bool_t nbnsCompareName	(	const NbnsHeader *	message,
		size_t	length,
		size_t	pos,
		const char_t *	name
	)

Compare NetBIOS names.

Parameters

[in]	message	Pointer to the NBNS message
[in]	length	Length of the NBNS message
[in]	pos	Offset of the encoded domain name
[in]	name	NULL-terminated string that holds a domain name

Returns

TRUE if the NetBIOS names match, else FALSE

Definition at line 284 of file nbns_common.c.

nbnsEncodeName()

size_t nbnsEncodeName	(	const char_t *	src,
		uint8_t *	dest
	)

Encode a NetBIOS name.

Parameters

[in]	src	Pointer to the name to encode
[out]	dest	Pointer to the encoded NetBIOS name

Returns

Length of the encoded NetBIOS name

Definition at line 148 of file nbns_common.c.

nbnsInit()

error_t nbnsInit

(

NetInterface *

interface

)

NBNS related initialization.

Parameters

[in]

interface

Underlying network interface

Returns

Error code

Definition at line 53 of file nbns_common.c.

nbnsParseName()

size_t nbnsParseName	(	const NbnsHeader *	message,
		size_t	length,
		size_t	pos,
		char_t *	dest
	)

Decode a NetBIOS name.

Parameters

[in]	message	Pointer to the NBNS message
[in]	length	Length of the NBNS message
[in]	pos	Offset of the name to decode
[out]	dest	Pointer to the decoded name (optional)

Returns

The position of the resource record that immediately follows the NetBIOS name

Definition at line 200 of file nbns_common.c.

nbnsProcessMessage()

void nbnsProcessMessage	(	NetInterface *	interface,
		const IpPseudoHeader *	pseudoHeader,
		const UdpHeader *	udpHeader,
		const NetBuffer *	buffer,
		size_t	offset,
		const NetRxAncillary *	ancillary,
		void *	param
	)

Process incoming NBNS message.

Parameters

[in]	interface	Underlying network interface
[in]	pseudoHeader	UDP pseudo header
[in]	udpHeader	UDP header
[in]	buffer	Multi-part buffer containing the incoming NBNS message
[in]	offset	Offset to the first byte of the NBNS message
[in]	ancillary	Additional options passed to the stack along with the packet
[in]	param	Callback function parameter (not used)
