# MLNLFFIGen

`mlnlffigen` generates a MLNLFFI binding from a collection of `.c` files. It is based on the CKitLibrary, which is primarily designed to handle standardized C and thus does not understand many (any?) compiler extensions; however, it attempts to recover from errors when seeing unrecognized definitions.

In order to work around common gcc extensions, it may be useful to add `-cppopt` options to the command line; for example `-cppopt '-Dextension'` may be occasionally useful. Fortunately, most portable libraries largely avoid the use of these types of extensions in header files.

`mlnlffigen` will normally not generate bindings for `#included` files; see `-match` and `-allSU` if this is desirable.
