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

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. ATTRIBUTES
