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_TENTATIVE_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.
