NAME¶clGetCommandQueueInfo - Query information about a command-queue.
cl_int clGetCommandQueueInfo(cl_command_queue command_queue, cl_command_queue_info param_name, size_t param_value_size, void *param_value, size_t *param_value_size_ret);
|cl_command_queue_info||Return Type and Information returned in param_value|
|CL_QUEUE_CONTEXT||Return type: cl_context Return the context specified when the command-queue is created.|
|CL_QUEUE_DEVICE||Return type: cl_device_id Return the device specified when the command-queue is created.|
|CL_QUEUE_REFERENCE_COUNT||Return type: cl_uint Return the command-queue reference count. CL_QUEUE_REFERENCE_COUNT should be considered immediately stale. It is unsuitable for general use in applications. This feature is provided for identifying memory leaks.|
|CL_QUEUE_PROPERTIES||Return type: cl_command_queue_properties Return the currently specified properties for the command-queue. These properties are specified by the properties argument in clCreateCommandQueue(3clc).|
NOTES¶It is possible that a device(s) becomes unavailable after a context and command-queues that use this device(s) have been created and commands have been queued to command-queues. In this case the behavior of OpenCL API calls that use this context (and command-queues) are considered to be implementation-defined. The user callback function, if specified, when the context is created can be used to record appropriate information in the errinfo, private_info arguments passed to the callback function when the device becomes unavailable.
ERRORS¶Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns the following:
