clEnqueueWaitForEvents

Enqueues a wait for a specific event or a list of events to complete before any future commands queued in the command-queue are executed.

cl_int clEnqueueWaitForEvents ( cl_command_queue command_queue,
  cl_uint num_events,
  const cl_event *event_list)

Parameters

command_queue

A valid command-queue.

num_events

Specifies the number of events given by event_list.

*event_list

Events specified in event_list act as synchronization points. Each event in event_list must be a valid event object returned by a previous call to the following:

Notes

The context associated with events in event_list and command_queue must be the same.

Errors

Returns CL_SUCCESS if the function was successfully executed, or one of the errors below:

  • CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue.
  • CL_INVALID_CONTEXT if the context associated with command_queue and events in event_list are not the same.
  • CL_INVALID_VALUE if num_events is zero or event_list is NULL.
  • CL_INVALID_EVENT if event objects specified in event_list are not valid events.
  • CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.
