DAT_PSP_FREE(3DAT) Direct Access Transport Library Functions

NAME

dat_psp_free - destroy an instance of the Public Service Point

SYNOPSIS

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

DAT_RETURN
dat_psp_free (
IN DAT_PSP_HANDLE psp_handle
)

PARAMETERS

psp_handle
Handle for an instance of the Public Service Point.

DESCRIPTION

The dat_psp_free() function destroys a specified instance of the
Public Service Point.


Any incoming Connection Requests for the Connection Qualifier on the
destroyed Service Point it had been listening on are automatically
rejected by the Provider with the return analogous to the no
listening Service Point.


The behavior of the Connection Requests in progress is undefined and
left to an implementation. But it must be consistent. This means that
either a Connection Requested Event has been generated for the Event
Dispatcher associated with the Service Point, including the creation
of the Connection Request instance, or the Connection Request is
rejected by the Provider without any local notification.


This operation shall have no effect on previously generated
Connection Requested Events. This includes Connection Request
instances and, potentially, Endpoint instances created by the
Provider.


The behavior of this operation with creation of a Service Point on
the same Connection Qualifier at the same time is not defined.
Consumers are advised to avoid this scenario.


Use of the handle of the destroyed Public Service Point in any
consequent operation fails.

RETURN VALUES

DAT_SUCCESS
The operation was successful.


DAT_INVALID_HANDLE
The psp_handle parameter is invalid.
