package lintcstubs-arity

Install:

opam install lintcstubs-arity

Usage:

lintcstubs_arity ocamlfile.ml >primitives.h

ocamlfile.ml is an OCaml file that declares a C primitive as defined in the manual. Once primitives.h is generated you can include it in the .c files that implement the OCaml primitives defined in ocamlfile.ml.

This can help detect simple mismatches between the number of arguments declared in the .ml file and implemented in the .c file. It is recommended to include the above generation step in the build process of the C stubs.
