Subject: [Caml-list] Some questions regarding OCaml FFI
Date: Mon, 03 Apr 2017 01:58:42 +0300	[thread overview]
Message-ID: <1491173922.446722065@f400.i.mail.ru> (raw)

Hello,

I have some questions about OCaml FFI:

1) Should I declare local variable with CAMLlocalN if its used "temporarily", for example:
CAMLreturn(Val_long(1));
vs
CAMLlocal1(longval);
longval = Val_long(1);
CAMLreturn(longval);

2) Should I call 'caml_acquire_runtime_system()' prior to calling OCaml functions from C main()? If so - should I call it before or after 'caml_startup()'?

Thanks!
