Returns the number of local work-items.
size_t get_local_size(uint dimindx);
Returns the number of local work-items specified in dimension identified by dimindx. This value is given by the local_work_size argument to clEnqueueNDRangeKernel(3clc) if local_work_size is not NULL; otherwise the OpenCL implementation chooses an appropriate local_work_size value which is returned by this function. Valid values of dimindx are 0 to get_work_dim(3clc)() - 1. For other values of dimindx, get_local_size() returns 1.
For clEnqueueTask(3clc), this always returns 1.
