 DAT_EP_RESET 3DAT "Jul 16, 2004"
 NAME
dat_ep_reset - transition the local Endpoint from a Disconnected to an
Unconnected state
 SYNOPSIS

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

DAT_RETURN
 dat_ep_reset (
 IN DAT_EP_HANDLE ep_handle
 )


 PARAMETERS
ep_handle

Handle for an instance of Endpoint.


 DESCRIPTION

The dat_ep_reset() function transitions the local Endpoint from a
Disconnected to an Unconnected state.

The operation might cause the loss of any completions of previously posted DTOs
and RMRs that were not dequeued yet.

The dat_ep_reset() function is valid for both Disconnected and
Unconnected states. For Unconnected state, the operation is no-op because the
Endpoint is already in an Unconnected state. For an Unconnected state, the
preposted Recvs are not affected by the call.
 RETURN VALUES
DAT_SUCCESS

The operation was successful.


DAT_INVALID_HANDLE

ep_handle is invalid.


DAT_INVALID_STATE

Parameter in an invalid state. Endpoint is not in the valid state for reset.


 USAGE

If the Consumer wants to ensure that all Completions are dequeued, the Consumer
can post DTO or RMR operations as a "marker" that are flushed to
recv_evd_handle or request_evd_handle. Now, when the Consumer
dequeues the completion of the "marker" from the EVD, it is guaranteed that all
previously posted DTO and RMR completions for the Endpoint were dequeued for
that EVD. Now, it is safe to reset the Endpoint without losing any
completions.
