NAME

       dat_ep_free - destroy an instance of the Endpoint

SYNOPSIS

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

       DAT_RETURN
	   dat_ep_free (
	   IN	 DAT_EP_HANDLE	  ep_handle
	   )

PARAMETERS

       ep_handle    Handle for an instance of the Endpoint.

DESCRIPTION

       The dat_ep_free() function destroys an instance of the Endpoint.

       The  Endpoint  can  be  destroyed  in any Endpoint state except Reserved, Passive Connection Pending, and Tentative Connection Pending. The
       destruction of the Endpoint can also cause the destruction of DTOs and RMRs posted to the Endpoint and not dequeued yet. This includes com-
       pletions  for  all  outstanding	and in-progress DTOs/RMRs. The Consumer must be ready for all completions that are not dequeued yet either
       still being on the Endpoint recv_evd_handle and request_evd_handle or not being there.

       The destruction of the Endpoint during connection setup aborts connection establishment.

       If the Endpoint is in the Reserved state, the Consumer shall first destroy the associated Reserved Service Point that transitions the  End-
       point  into the Unconnected state where the Endpoint can be destroyed. If the Endpoint is in the Passive Connection Pending state, the Con-
       sumer shall first reject the associated Connection Request that transitions the Endpoint into the Unconnected state where the Endpoint  can
       be  destroyed.  If  the	Endpoint is in the Tentative Connection Pending state, the Consumer shall reject the associated Connection Request
       that transitions the Endpoint back to Provider control, and the Endpoint is destroyed as far as the Consumer is concerned.

       The freeing of an Endpoint also destroys an Event Stream for each of the associated Event Dispatchers.

       Use of the handle of the destroyed Endpoint in any subsequent operation except for the dat_ep_free() fails.

RETURN VALUES

       DAT_SUCCESS	     The operation was successful.

       DAT_INVALID_HANDLE    The ep_handle parameter is invalid.

       DAT_INVALID_STATE     Parameter in an invalid state. The Endpoint is in DAT_EP_STATE_RESERVED, DAT_EP_STATE_PASSIVE_CONNECTION_PENDING,	or
			     DAT_EP_STATE_TENTATIVE_CONNECTION_PENDING.
