EapPeerGetResponsePacket function

Obtains a response packet from the EAP method.


DWORD WINAPI EapPeerGetResponsePacket(
  _In_    EAP_SESSION_HANDLE sessionHandle,
  _Inout_ DWORD              *pcbSendPacket,
  _Out_   EapPacket          *pSendPacket,
  _Out_   EAP_ERROR          **ppEapError


sessionHandle [in]

A pointer to an EAP_SESSION_HANDLE structure that contains the unique handle for this EAP authentication session on the EAPHost server. This handle is returned in the pSessionHandle parameter in a previous call to EapPeerBeginSession.

pcbSendPacket [in, out]

A pointer to a value that contains the size in bytes of the buffer allocated for the response packet. On return, this parameter receives a pointer to the actual size in bytes of pSendPacket.

pSendPacket [out]

A pointer to an EapPacket structure that contains the response packet.

ppEapError [out]

A pointer to the address of an EAP_ERROR structure that contains any errors raised during the execution of this function call. After consuming the error data, this memory must be freed by callingEapPeerFreeErrorMemory.


EapPeerGetResponsePacket is called by EAPHost on the EAP method to obtain a response packet. EAPHost only calls this API when the action code from a prior call indicates that a packet is available.

This call is performed by a peer-based EAPHost using a function pointer to this API. This API must be implemented on the EAP method loaded by EAPHost, and must strictly conform to the syntax and parameter types specified in the documentation.
