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 trans-
	    port mandated RTU messages. This includes binding it to the IA port if that was not done previously. The Consumer is notified 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.
