NAME

       dat_psp_create_any - create a persistent Public Service Point

SYNOPSIS

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

       DAT_RETURN
	   dat_psp_create_any(
	   IN	 DAT_IA_HANDLE	  ia_handle,
	   IN	 DAT_CONN_QUAL	  conn_qual,
	   IN	 DAT_EVD_HANDLE   evd_handle,
	   IN	 DAT_PSP_FLAGS	  psp_flags,
	   OUT	 DAT_PSP_HANDLE   *psp_handle
	   )

PARAMETERS

       ia_handle     Handle for an instance of DAT IA.

       conn_qual     Connection Qualifier of the IA on which the Public Service Point is listening.

       evd_handle    Event  Dispatcher	that  provides	the Connection Requested Events to the Consumer. The size of the event queue for the Event
		     Dispatcher controls the size of the backlog for the created Public Service Point.

       psp_flags     Flag that indicates whether the Provider or Consumer creates an  Endpoint	per  arrived  Connection  Request.  The  value	of
		     DAT_PSP_PROVIDER  indicates  that	the Consumer wants to get an Endpoint from the Provider; a value of DAT_PSP_CONSUMER means
		     the Consumer does not want the Provider to provide an Endpoint for each arrived Connection Request.

       psp_handle    Handle to an opaque Public Service Point.

DESCRIPTION

       The dat_psp_create_any() function creates a persistent Public Service Point that can receive multiple requests for connection and  generate
       multiple Connection Request instances that are delivered through the specified Event Dispatcher in Notification events.

       The  dat_psp_create_any()  function  allocates  an unused Connection Qualifier, creates a Public Service point for it, and returns both the
       allocated Connection Qualifier and the created Public Service Point to the Consumer.

       The allocated Connection Qualifier should be chosen from "nonprivileged" ports that are not currently used or reserved by any user or  ker-
       nel Consumer or host ULP of the IA. The format of allocated Connection Qualifier returned is specific to IA transport type.

       The  dat_psp_create_any()  function  is	blocking. When the Public Service Point is created, DAT_SUCCESS is returned, psp_handle contains a
       handle to an opaque Public Service Point Object, and conn_qual contains the allocated Connection Qualifier. When return is not DAT_SUCCESS,
       psp_handle and conn_qual return values are undefined.

       There  is  no explicit backlog for a Public Service Point. Instead, Consumers can control the size of backlog through the queue size of the
       associated Event Dispatcher.

       The psp_flags parameter allows Consumers to request that the Provider create an implicit Endpoint for each incoming Connection Request,	or
       request	that  the  Provider  should not create one per Connection Request. If the Provider cannot satisfy the request, the operation shall
       fail and DAT_MODEL_NOT_SUPPORTED is returned.

       All Endpoints created by the Provider have DAT_HANDLE_NULL  for the Protection Zone and all Event Dispatchers. The Provider  sets  up  End-
       point attributes to match the Active side connection request. The Consumer can change Endpoint parameters. Consumers should change Endpoint
       parameters, especially PZ and EVD, and are advised to change parameters for local accesses prior to the connection request acceptance  with
       the Endpoint.

RETURN VALUES

       DAT_SUCCESS		     The operation was successful.

       DAT_INSUFFICIENT_RESOURCES    The operation failed due to resource limitations.

       DAT_INVALID_HANDLE	     The ia_handle or evd_handle parameter is invalid.

       DAT_INVALID_PARAMETER	     The conn_qual or psp_flags parameter is invalid.

       DAT_CONN_QUAL_UNAVAILABLE     No Connection Qualifiers available.

       DAT_MODEL_NOT_SUPPORTED	     The requested Model was not supported by the Provider.
