Provides port addresses which fully differentiate ports within a particular service. A port address includes:

• The port number, which uniquely identifies this port at this interface.
• The interface address, which identifies this interface within the scope of the service.

The general address structure is large enough so that known interface addressing schemes will fit within the fields shown.

This structure's fields are large enough to accommodate known interface addressing schemes.

Syntax

typedef struct tagGenAddr {
    BYTE byAddressLen;
    BYTE byNotUsed;
    WORD wPortID;
    BYTE Address[28];
} GENADDR, *LPGENADDR;

Fields

byAddressLen

Indicates the number of valid bytes in the address field (fixed for a given service, and given in the service descriptor).

byNotUsed

This field is not used by the kernel.

wPortID

The port number part of the port address.

Address

The interface address part of the port address.
