dat_ep_query(3DAT) Direct Access Transport Library Functions dat_ep_query(3DAT) 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. ATTRIBUTES

dat_ep_free(3DAT) Direct Access Transport Library Functions dat_ep_free(3DAT) 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. ATTRIBUTES
