taron_31 | Hello all,
j'ai commencé a programmer un messenger en C avec la bibliothèque GTK+, le problème est que le code ne fonctionne pas (je ne sais pas vraiment a quel niveau), mais il se compile. Je n'arrive pas tellement a vous expliquer mon problème, moi même j'ai du mal a comprendre, ça doit surement venir de code, le voici :
Code :
- /* Main C file */
- #include <stdio.h>
- #include <gtk/gtk.h> /* Headers */
- #include <winsock2.h>
- #include "infos.h" /* Infos about Alaum product */
- #define MAX_RECV 512
- #define NO_SENT "Your message has not been sent !"
- #define SENT "Your message has been sent !"
- #define PORT_DEFAULT 4666
- #define IP_DEFAULT "127.0.0.1"
- #define CONNECTED 0
- #define ABORTED 1
- /* Prototypes functions */
- short socket_create(); // Create 2 socekt (server & client)
- void OnEnter_Send(GtkWidget *, gpointer); /* Callbacks for GTK+ */
- void OnClick_Send(GtkWidget *, gpointer);

- SOCKADDR_IN server_sockad, client_sockad, friend_sockad; // sockaddr_in objects declaration
- int socket_server, socket_client, friend_socket, friend_size; // socket description declaration
- int main(int argc, char *argv[])

Plus exactement, le problème est que la connexion ne se réalise pas entre 2 programmes...
Pouvez-vous m'éclaircir un peu s'il vous plaît ?
Merci |
