Public Members

uint64_t field_mask

Mask of valid fields in this structure, using bits from ucp_ep_attr_field. Fields not specified in this mask will be ignored. Provides ABI compatibility with respect to adding new fields.

char name[UCP_ENTITY_NAME_MAX]

Endpoint name. Tracing and analysis tools can identify the endpoint using this name.

struct sockaddr_storage local_sockaddr

Local socket address for this endpoint. Valid only for endpoints created by connecting to a socket address. If this field is specified for an endpoint not connected to a socket address, UCS_ERR_NOT_CONNECTED will be returned.

struct sockaddr_storage remote_sockaddr

Remote socket address this endpoint is connected to. Valid only for endpoints created by connecting to a socket address. If this field is specified for an endpoint not connected to a socket address, UCS_ERR_NOT_CONNECTED will be returned.

ucp_transports_t transports

Structure defining an array containing transport and device names used by this endpoint. The caller is responsible for allocation and deallocation of this array.
