  • Article

The WCN_VENDOR_EXTENSION_SPEC structure contains data that defines a vendor extension.

Syntax

typedef struct tagWCN_VENDOR_EXTENSION_SPEC {
  DWORD VendorId;
  DWORD SubType;
  DWORD Index;
  DWORD Flags;
} WCN_VENDOR_EXTENSION_SPEC;

Members

VendorId

Set this value to the SMI Enterprise ID Number of the vendor that defines the vendor extension. For example, the Microsoft ID is '311' (WCN_MICROSOFT_VENDOR_ID).

SubType

The subtype, as defined by the first two bytes of the vendor extension. If the vendor has not provided the two-byte subtype prefix, use WCN_NO_SUBTYPE.

Index

Distinguishes between multiple vendor extensions with the same VendorID and SubType. The index begins at zero.

WCN_FLAG_ENCRYPTED_VE
