Subject: | Interfacing C procedure using an array as parameter ? |
[French version at the bottom] Hello all, Firstly, thanks to those of you who provided me with information about C++/OCaml interfacing, this has been very usefull. This is the first time I interface C/OCaml and also I have a problem : How do I use a parameter which is a pointer on the beginning of an integer array ? The C prototype : ---------------- void EndConfig(int *tid, int nb_tids); /* tid is a pointer on an array of task id nb_tids is the number of task id in the array */ the Caml interface : ------------------- external end_config : int vect -> unit;; value end_config(tids) value tids; { /* what do I put here ? */ } Though the RM provides an example with return list (p.122-3) I am a bit lost regarding the use of vectors. Thanks for any help, Vincent. [Version francaise] Bonjour at tous, Tout d'abord merci aux personnes qui m'ont fourni des informations a propos de l'interfacing de C++/OCaml, elles ont ete tres utiles. C'est la premiere fois que j'interface C/OCaml et aussi j'ai un probleme : Comment utiliser un argument qui est un pointeur sur le debut d'un tableau d'entiers ? Le prototypage C : ----------------- void EndConfig(int *tid, int nb_tids); /* tid is a pointer on an array of task id nb_tids is the number of task id in the array */ l'interface Caml : ----------------- external end_config : int vect -> unit;; value end_config(tids) value tids; { /* que dois-je mettre ici ? */ } Bien que j'ai trouve un exemple dans le MR avec un retour de liste (p.122-3) je suis un peu perdu en ce qui concerne l'utilisation des vectors. Merci pour votre aide, Vincent. ______________________________________________________________ Vincent B.G.Leleu Parallel Computing Research Centre Anglia Polytechnic University Victoria Rd.
