NDIS_TAPI_SEND_USER_USER_INFO (Windows Embedded CE 6.0)

1/6/2010

OID_TAPI_SEND_USER_USER_INFO uses the NDIS_TAPI_SEND_USER_USER_INFO structure when it requests the miniport driver to send user-to-user information to the remote party on the specified call.

Support for this request is optional.

Syntax

typedef struct _NDIS_TAPI_SEND_USER_USER_INFO { 
  ULONG ulRequestID; 
  HDRV_CALL hdCall; 
  ULONG ulUserUserInfoSize; 
  UCHAR UserUserInfo[1]; 
} NDIS_TAPI_SEND_USER_USER_INFO, *PNDIS_TAPI_SEND_USER_USER_INFO; 

Members

• ulRequestID
  [in] Reserved.

• hdCall
  [in] Specifies the miniport driver's handle to the call on which to send user-to-user information.

• ulUserUserInfoSize
  [in] Specifies the size in bytes of the UserUserInfo string.

• UserUserInfo

• NDIS_STATUS_SUCCESS
• NDIS_STATUS_PENDING
• NDIS_STATUS_TAPI_INVALCALLHANDLE
• NDIS_STATUS_TAPI_INVALCALLSTATE
