MACFRAME union

The MACFRAME structure is a union of the most common initial protocols.

Syntax

typedef union {
  LPBYTE      MacHeader;
  LPETHERNET  Ethernet;
  LPTOKENRING Tokenring;
  LPFDDI      Fddi;
} MACFRAME, *LPMACFRAME;

Members

MacHeader

Generic pointer to a frame.

Ethernet

Ethernet pointer to a frame.

Tokenring

Token ring pointer to a frame.

Fddi

FDDI pointer to a frame.

Remarks

This structure is most frequently used as an overlay. To make the properties of the first protocol accessible, cast the frame as the same type as the protocol.
