Développement d'une extension PHP

Bonjour,
je suis en train de developper un generateur d'extension php en python à partir d'un fichier gabarit XML.
j'aimerais simplement savoir si je suis sur la bonne voie pour créer mon extension, la question ne porte pas sur le generateur python mais sur les fichiers d'extensions php que je genere :
il y en a 2 que je genere :

- module.c
- php_module.h

ma question porte d'abord sur le fichier php_module.h, je voudrais savoir si il est correctement généré (honetement j'ai du mal a comprendre les fonctions de l'API ZEND) je me suis basé sur different tutos et jai aussi regardé les differentes extensions deja intégré à PHP, voici mon code généré :

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79

avant de m'attaquer a la generation du fichier d'implementation module.c, ce fichier deja est t'il bon ? y a t'il des erreurs ?

j'aimerais aussi savoir quel type en PHP remplace ce type de structure en C :

Code:

---

1 2 3 4 5

typedef struct { net_int_t arg; /*< An argument. */ } test_module_params;

---

ou tout autre structure d'ailleurs ! sachant que les types en PHP sont :

Boolean, Long, Double, String, Resources, Array, Object.

merci d'avance.

Je continue de galerer mais j'avance un peu voici mon header :

Code:

je crois qu'il est tout bon, a part mes types perso 'net_int_t', 'net_char_t', je ne sais pas encore si je peux les laisser , en tout cas, ils sont definis dans net_type.h.

mon fichier c maintenant :

ici c'est plus complexe, j'ai déclaré donc 2 structures globales dans le header et je les initialise a l'appel de la fonction MINIT_FUNCTION.
- Est ce que je dois laisser les lignes 'arginfo', pour defnir les arguments de chaque fonctions ?
- mes pointeurs de structures dans les fonctions php peuvent ils etre laissé comme ca, est ce que je dois utiliser plutot zval * ?

merci d'avance :roll:
