The Felix binding generates C. So the answer is, the same way as you would in C.

However the above is a low level binding, one to one with C. 
Higher level stuff is possible. Won’t know until the binding is operational.
My script is basically working translating the *.pxd files in Cython.
(Just the functions, the rest can be done by hand).

Basically I can write, say, a concurrent matrix multiplication routine and
map it to Python. Of course you can do that in C as well, but Felix is a very
high level language so you can do stuff you wouldn’t bother attempting
in low level languages like C and C++.
