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 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() - 1. For other
values of dimindx
, get_local_size
() returns 1.
For clEnqueueTask, this always returns 1.
