NAME

       dat_ep_query - provide parameters of the Endpoint

SYNOPSIS

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

       DAT_RETURN
	   dat_ep_query (
	   IN	 DAT_EP_HANDLE	      ep_handle,
	   IN	 DAT_EP_PARAM_MASK    ep_param_mask,
	   OUT	 DAT_EP_PARAM	      *ep_param
	   )

PARAMETERS

       ep_handle	Handle for an instance of the Endpoint.

       ep_param_mask	Mask for Endpoint parameters.

       ep_param 	Pointer to a Consumer-allocated structure that the Provider fills with Endpoint parameters.

DESCRIPTION

       The dat_ep_query() function provides the Consumer parameters, including attributes and status, of the Endpoint. Consumers pass in a pointer
       to Consumer-allocated structures for Endpoint parameters that the Provider fills.

       The ep_param_mask parameter allows Consumers to specify which parameters to query. The Provider returns values for ep_param_mask  requested
       parameters. The Provider can return values for any other parameters.

       Some  of  the  parameters only have values for certain Endpoint states. Specifically, the values for remote_ia_address and remote_port_qual
       are valid only for Endpoints in the  DAT_EP_STATE_PASSIVE_CONNECTION_PENDING,  DAT_EP_STATE_ACTIVE_CONNECTION_PENDING,  DAT_EP_STATE_TENTA-
       TIVE_CONNECTION_PENDING,  DAT_EP_STATE_DISCONNECT_PENDING, DAT_EP_STATE_COMPLETION_PENDING, or DAT_EP_STATE_CONNECTED states. The values of
       local_port_qual is  valid  only	for  Endpoints	in  the  DAT_EP_STATE_PASSIVE_CONNECTION_PENDING,  DAT_EP_STATE_ACTIVE_CONNECTION_PENDING,
       DAT_EP_STATE_DISCONNECT_PENDING,   DAT_EP_STATE_COMPLETION_PENDING,   or   DAT_EP_STATE_CONNECTED   states,   and   might   be	valid  for
       DAT_EP_STATE_UNCONNECTED, DAT_EP_STATE_RESERVED,  DAT_EP_STATE_TENTATIVE_CONNECTION_PENDING,  DAT_EP_STATE_PASSIVE_CONNECTION_PENDING,  and
       DAT_EP_STATE_UNCONNECTED states.

RETURN VALUES

       DAT_SUCCESS		The operation was successful.

       DAT_INVALID_HANDLE	The ep_handle parameter is invalid.

       DAT_INVALID_PARAMETER	The ep_param_mask parameter is invalid.

NAME

       dat_ep_get_status - provide a quick snapshot of the Endpoint

SYNOPSIS

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

       DAT_RETURN
	   dat_ep_get_status (
	   IN	 DAT_EP_HANDLE	  ep_handle,
	   OUT	 DAT_EP_STATE	  *ep_state,
	   OUT	 DAT_BOOLEAN	  *recv_idle,
	   OUT	 DAT_BOOLEAN	  *request_idle
	   )

PARAMETERS

       ep_handle       Handle for an instance of the Endpoint.

       ep_state        Current state of the Endpoint.

       recv_idle       Status of the incoming DTOs on the Endpoint.

       request_idle    Status of the outgoing DTOs and RMR Bind operations on the Endpoint.

DESCRIPTION

       the  dat_ep_get_status()  function  provides the Consumer a quick snapshot of the Endpoint. The snapshot consists of the Endpoint state and
       whether there are outstanding or in-progress, incoming or outgoing DTOs. Incoming DTOs consist of Receives. Outgoing DTOs  consist  of  the
       Requests, Send, RDMA Read, RDMA Write, and RMR Bind.

       The  ep_state  parameter  returns  the  value  of  the  current	state  of  the	Endpoint  ep_handle.  State value is one of the following:
       DAT_EP_STATE_UNCONNECTED,    DAT_EP_STATE_RESERVED,    DAT_EP_STATE_PASSIVE_CONNECTION_PENDING,	   DAT_EP_STATE_ACTIVE_CONNECTION_PENDING,
       DAT_EP_STATE_TENTATIVE_CONNECTION_PENDING, DAT_EP_STATE_CONNECTED, DAT_EP_STATE_DISCONNECT_PENDING, or DAT_EP_STATE_DISCONNECTED.

       A recv_idle value of DAT_TRUE specifies that there are no outstanding or in-progress Receive DTOs at the Endpoint, and DAT_FALSE otherwise.

       A request_idle value of DAT_TRUE specifies that there are no outstanding or in-progress Send, RDMA Read, and RDMA Write DTOs, and RMR Binds
       at the Endpoint, and DAT_FALSE otherwise.

       This call provides a snapshot of the Endpoint status only. No heroic synchronization with DTO queuing or processing is implied.

RETURN VALUES

       DAT_SUCCESS	     The operation was successful.

       DAT_INVALID_HANDLE    The ep_handle parameter is invalid.
