Method set_callback

include/boost/compute/event.hpp:229–239

Registers a function to be called when the event status changes to \p status (by default CL_COMPLETE). The callback is passed the OpenCL event object, the event status, and a pointer to arbitrary user data. \see_opencl_ref{clSetEventCallback} \opencl_version_warning{1,1}
