cffi / README.md


Foreign Function Interface for Python calling C code.

Mailing list: https://groups.google.com/forum/#!forum/python-cffi

Initial motivation


Current status

  • works as a ctypes replacement
  • can use internally either ctypes or a C extension module

Next steps

the verify() step, which should handle:

  • completing "...;" structs

  • checking the other structs, and the arguments to functions, using the real C compiler

  • simple "#define FOO value" macros

  • macros of the kind "#define funcname otherfuncname"

  • more complicated macros "#define foo(a, b, c) ..."

  • checking and correcting the value of the enum {} declarations

  • probably also fixing the array lengths, e.g. declared as a field "int foo[...];"

generating C extensions:

  • this is needed anyway to call macros

  • faster, libffi-free way to call C code

  • partial blockers: callbacks (probably still use libffi)
