Main mode of usage ¶. The main way to use CFFI is as an interface to some already-compiled shared object which is provided by other means. Imagine that you have a system-installed shared object called piapprox.dll (Windows) or libpiapprox.so (Linux and others) or libpiapprox.dylib (OS X), exporting a function float pi_approx(int n); that computes some approximation of pi given a number of ...

CFFI can be used in one of four modes: “ABI” versus “API” level, each with “in-line” or “out-of-line” preparation (or compilation). The ABI mode accesses libraries at the binary level, whereas the faster API mode accesses them with a C compiler. We …
