[This documentation is preliminary and is subject to change.]

The CPNATFWT_PROVIDER_INSTANCE_DISPATCH_TABLE structure is a dispatch table with entry points for calls from the Connectivity Platform (CP) to the Provider.

Syntax

typedef struct _CPNATFWT_PROVIDER_INSTANCE_DISPATCH_TABLE {
  CPNATFWT_PROVIDER_ESTABLISH_SESSION_INDICATION establishSession;
  CPNATFWT_PROVIDER_TERMINATE_SESSION_INDICATION terminateSession;
  CPNATFWT_PROVIDER_TRANSITION_ACTIVE            transitionActive;
  CPNATFWT_PROVIDER_TRANSITION_DORMANT           transitionDormant;
  CPNATFWT_PROVIDER_ADD_TRANSPORT_ID             addTransportId;
  CPNATFWT_PROVIDER_REMOVE_TRANSPORT_ID          removeTransportId;
  CPNATFWT_PROVIDER_REACH_TRANSPORT_ID           reachTransportId;
  CPNATFWT_PROVIDER_SEND_BUFFERS                 sendBuffers;
} CPNATFWT_PROVIDER_INSTANCE_DISPATCH_TABLE;

Members

establishSession
A pointer to the Provider function that implements session establishment.
terminateSession
A pointer to the Provider function that implements session termination .
transitionActive
A pointer to the Provider function that implements the transition to an active state.
transitionDormant
A pointer to the Provider function that implements the transition to a dormant state.
addTransportId
A pointer to the Provider function that implements the addition of a transport ID.
removeTransportId
A pointer to the Provider function that implements the removal of a transport ID.
reachTransportId
A pointer to the Provider function that implements a check if a transport ID can be reached.
sendBuffers
A pointer to the Provider function that implements sending buffers.

Remarks

The CPNATFWT_PROVIDER_INSTANCE_DISPATCH_TABLE structure is used by the Connectivity Platform feature supported on Windows 7 and later.

The Connectivity Platform (CP) provides a mechanism for specialized applications and services to provide custom network traversal of network address translation (NAT) and firewalls on Windows 7 and later. A Provider registers with the Connectivity Platform to provide network traversal for other applications that use standard Windows networking APIs such as Windows Sockets.

The CPNATFWT_PROVIDER_INSTANCE_DISPATCH_TABLE structure is a dispatch table with entry points for calls from the Connectivity Platform to the Provider. This structure is passed to the CPNatfwtCreateProviderInstance function when a Provider registers with CP.
