The WSAPROTOCOLCHAIN structure contains a counted list of Catalog Entry identifiers that comprise a protocol chain.
typedef struct _WSAPROTOCOLCHAIN {
int ChainLen;
DWORD ChainEntries[MAX_PROTOCOL_CHAIN];
} WSAPROTOCOLCHAIN, *LPWSAPROTOCOLCHAIN;
ChainLen
Length of the chain, in bytes. The following settings apply:
Setting ChainLen to zero indicates a layered protocol
Setting ChainLen to one indicates a base protocol
Setting ChainLen to greater than one indicates a protocol chain
ChainEntries
Array of protocol chain entries.
If the length of the chain is larger than 1, this structure represents a protocol chain which consists of one or more layered protocols on top of a base protocol. The corresponding Catalog Entry IDs are in the ProtocolChain.ChainEntries array starting with the layered protocol at the top (the zeroth element in the ProtocolChain.ChainEntries array) and ending with the base protocol. Refer to Windows Sockets 2 Service Provider Interface for more information on protocol chains.
