A dummy Racket function that refers callers to the other -based functions which access the true C function.
Returns the size of param_name field of the argument(s). Calls with values for param_value_size and param_value such that param_value_size_ret is queried.
Returns the value associated with param_name for the argument(s). Implemented by with param_value_size set to (ctype-sizeof ) so that the value is queried. Valid param_names are '(CL_PROFILING_COMMAND_QUEUED CL_PROFILING_COMMAND_SUBMIT CL_PROFILING_COMMAND_START CL_PROFILING_COMMAND_END).
A contract for the return values of . Its definition is: (or/c ).
Returns the value associated with param_name for the argument(s). Selects the appropriate -based function to extract the appropriate value, automatically providing the right length for variable length functions.
