NAME

       dat_rsp_create - create a Reserved Service Point

SYNOPSIS

       cc [ flag... ] file... -ldat [ library... ]
       #include <dat/udat.h>

       DAT_RETURN
	   dat_rsp_create (
	   IN	 DAT_IA_HANDLE	  ia_handle,
	   IN	 DAT_CONN_QUAL	  conn_qual,
	   IN	 DAT_EP_HANDLE	  ep_handle,
	   IN	 DAT_EVD_HANDLE   evd_handle,
	   OUT	 DAT_RSP_HANDLE   *rsp_handle
	   )

PARAMETERS

       ia_handle     Handle for an instance of DAT IA.

       conn_qual     Connection Qualifier of the IA the Reserved Service Point listens to.

       ep_handle     Handle  for  the  Endpoint  associated with the Reserved Service Point that is the only Endpoint that can accept a Connection
		     Request on this Service Point. The value DAT_HANDLE_NULL requests the Provider to associate a Provider-created Endpoint  with
		     this Service Point.

       evd_handle    The Event Dispatcher to which an event of Connection Request arrival is generated.

       rsp_handle    Handle to an opaque Reserved Service Point.

DESCRIPTION

       The  dat_rsp_create() function creates a Reserved Service Point with the specified Endpoint that generates, at most, one Connection Request
       that is delivered to the specified Event Dispatcher in a Notification event.

RETURN VALUES

       DAT_SUCCESS		     The operation was successful.

       DAT_INSUFFICIENT_RESOURCES    The operation failed due to resource limitations.

       DAT_INVALID_HANDLE	     The ia_handle, evd_handle, or ep_handle parameter is invalid.

       DAT_INVALID_PARAMETER	     The conn_qual parameter is invalid.

       DAT_INVALID_STATE	     Parameter in an invalid state. For example, an Endpoint was not in the Idle state.

       DAT_CONN_QUAL_IN_USE	     Specified Connection Qualifier is in use.

USAGE

       The usage of a Reserve Service Point is as follows:

	   o	  The DAT Consumer creates a Local Endpoint and configures it appropriately.

	   o	  The DAT Consumer creates a Reserved Service Point specifying the Local Endpoint.

	   o	  The Reserved Service Point performs the following:

	       o      Collects native transport information reflecting a received Connection Request.

	       o      Creates a Pending Connection Request.

	       o      Creates a Connection Request Notice (event) that includes the Pending Connection	Request  (which  includes,  among  others,
		      Reserved Service Point Connection Qualifier, its Local Endpoint, and information about remote Endpoint).

	       o      Delivers the Connection Request Notice to the Consumer-specified target (CNO) evd_handle. The Local Endpoint is transitioned
		      from Reserved to Passive Connection Pending state.

	   o	  Upon receiving a connection request, or at some time subsequent to that, the DAT Consumer must either accept() or  reject()  the
		  Pending Connection Request.

	   o	  If  accepted,  the original Local Endpoint is now in a Connected state and fully usable for this connection, pending only native
		  transport mandated RTU messages. This includes binding it to the IA port if that was not done previously. The Consumer is  noti-
		  fied that the Endpoint is in a Connected state by a Connection Established Event on the Endpoint connect_evd_handle.

	   o	  If  rejected,  the Local Endpoint point transitions into Unconnected state. The DAT Consumer can elect to destroy it or reuse it
		  for other purposes.
