UCX_DEFAULT_ENDPOINT_EVENT_CALLBACKS_INIT function (ucxendpoint.h)

  • Article

Initializes a UCX_DEFAULT_ENDPOINT_EVENT_CALLBACKS structure with client driver's callback functions. The client driver calls this function before calling UcxEndpointCreate method to create an endpoint and register its callback functions with UCX.

Syntax

void UCX_DEFAULT_ENDPOINT_EVENT_CALLBACKS_INIT(
  [out] PUCX_DEFAULT_ENDPOINT_EVENT_CALLBACKS   Callbacks,
  [in]  PFN_UCX_ENDPOINT_PURGE                  EvtEndpointPurge,
  [in]  PFN_UCX_ENDPOINT_START                  EvtEndpointStart,

  [in]  PFN_UCX_DEFAULT_ENDPOINT_UPDATE         EvtDefaultEndpointUpdate
);
