Function Documentation

◆ nbnsCompareName()

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

Compare NetBIOS names.

Parameters
[in]messagePointer to the NBNS message
[in]lengthLength of the NBNS message
[in]posOffset of the encoded domain name
[in]nameNULL-terminated string that holds a domain name
Returns
TRUE if the NetBIOS names match, else FALSE

Definition at line 280 of file nbns_common.c.

◆ nbnsEncodeName()

size_t nbnsEncodeName ( const char_t src,
uint8_t *  dest 
)

Encode a NetBIOS name.

Parameters
[in]srcPointer to the name to encode
[out]destPointer to the encoded NetBIOS name
Returns
Length of the encoded NetBIOS name

Definition at line 144 of file nbns_common.c.

◆ nbnsInit()

error_t nbnsInit ( NetInterface interface)

NBNS related initialization.

Parameters
[in]interfaceUnderlying network interface
Returns
Error code

Definition at line 54 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]messagePointer to the NBNS message
[in]lengthLength of the NBNS message
[in]posOffset of the name to decode
[out]destPointer to the decoded name (optional)
Returns
The position of the resource record that immediately follows the NetBIOS name

Definition at line 196 of file nbns_common.c.

◆ nbnsProcessMessage()

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

Process incoming NBNS message.

Parameters
[in]interfaceUnderlying network interface
[in]pseudoHeaderUDP pseudo header
[in]udpHeaderUDP header
[in]bufferMulti-part buffer containing the incoming NBNS message
[in]offsetOffset to the first byte of the NBNS message
[in]paramCallback function parameter (not used)
