◆ 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 288 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 152 of file nbns_common.c.
◆ nbnsInit()
error_t nbnsInit | ( | NetInterface * | interface | ) |

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 204 of file nbns_common.c.
