Hi,
offsetof() is not supported by current Cython, and I have not found any workaround (except hardcoding offsets for a specific architecture and compiler, but this is obviously wrong).
offsetof() would certainly be very useful, but in the meantime offsetof(Struct, field) can be replaced with: <Py_ssize_t>&(<Struct*>NULL).field It's not ANSI C, but is portable enough. Another option (for extern or public structs only) is to abuse renaming: enum: Struct_offsetof_field1 "offsetof(Struct, field1)" This way a symbolic name can be given to any expression to be literally pasted into the generated code.
