"""
set_nthreads(nthreads)
Sets the number of threads to be used during bcolz operation.
This affects to both Blosc and Numexpr (if available). If you want to
change this number only for Blosc, use `blosc_set_nthreads` instead.
Parameters
----------
nthreads : int
The number of threads to be used during bcolz operation.
Returns
-------
out : int
The previous setting for the number of threads.
