GetFrameSourceAddress

The GetFrameSourceAddress function retrieves the source address of a frame.

DWORD WINAPIGetFrameSourceAddress(HFRAMEhFrame,
LPADDRESSlpAddress,
DWORDAddressType,
DWORDFlags);

Parameters

• hFrame
  A handle to the frame for which to get a pointer to.
• lpAddress
  A return buffer that stores the frame source address.
• AddressType
  The type of address searched for, such as ADDRESS_TYPE_ETHERNET or ADDRESS_TYPE_IP.
• Flags
  The flags used to modify returned source address data.

  Value	Meaning
  ADDRESSTYPE_FLAGS_NORMALIZE	Cancels the routing and group BITs.
  ADDRESSTYPE_FLAGS_BIT_REVERSE	Converts token ring network addresses back to normal.

Return Values

If the function is successful, the lpAddress value is valid, and the return value is BHERR_SUCCESS.

If the function is unsuccessful, the return value is an error code.

Remarks

An address type of ADDRESS_TYPE_FIND_HIGHEST is allowed. When this address type is used, the function searches for the IPX, XNS, IP, or VINES IP address before returning the ETHERNET, TOKENRING, or FDDI address. This approach is useful for protocols and environments in which two NICs can be multiplexed under a single server address.
