roromaino | bonjour,
J'ai recuperer sur le net un exemple d'envoie d'un fichier par email.
Lorsque je compile le programme avec borland 5.0, des erreurs se produisent dû au manque de certaines librairies.
voici le programme:
Code :
- #include <stdio.h>
- #include <stdlib.h>
- #include <unistd.h>
- #include <string.h>
- #include <netdb.h>
- #include <arpa/inet.h>
- #include <netinet/in.h>
- #include <sys/socket.h>
- #define DEBUG 0 /* Attention il y des pb si le msg envoye contient des % */
- #define PACKET_SIZE 1024
- void appli(char *f);
- int writen(int fd, char *ptr, int n);
- int readn(int fd, char *ptr, int n);
- int to_server_socket = -1;
- char server_name[] = "SERVEUR SMTP"; /* nom du host du serveur */
- int port = 25;
- char helo[] = "helo plus.bas\n";
- char from[] = "mail from: <nic@salemioche.com>\n";
- char to[] = "rcpt to: <ADDR DEST>\n";
- char subject[] = "Subject: transfert ";
- int main (int argc, char *argv[])

bref voici les librairies qui me manques :
Code :
- #include <unistd.h>
- #include <netdb.h>
- #include <arpa/inet.h>
- #include <netinet/in.h>
- #include <sys/socket.h>

où puis-je telecharger ces librairies, j'ai cherché sur le net, sans succes.
merci d'avance de vos reponses.
