RE: errors

["Yves Crespin" <Crespin dot Quartz at Wanadoo dot fr>]

The orignal code contains some errors ... but there's no compilation error.
Why compiler version are you using?
What compiler options?

	Yves

// Original code
        if ((sockfd = socket(AF_INET, SOCK_DGRAM, 0)) == -1) {
            perror("socket");
            exit(1);
        }

        their_addr.sin_family = AF_INET;     // host byte order
        their_addr.sin_port = htons(MYPORT); // short, network byte order
        their_addr.sin_addr = *((struct in_addr *)he->h_addr);
        memset(&(their_addr.sin_zero), '\0', 8); // zero the rest of the
struct

// Portable, "correct" and safe code
        if ((sockfd = socket(PF_INET, SOCK_DGRAM, 0)) == -1) {
            perror("socket");
            exit(1);
        }

        memset(&their_addr, 0, sizeof(their_addr)); // zero the struct
        their_addr.sin_family = AF_INET;     // host byte order
        their_addr.sin_port = htons(MYPORT); // short, network byte order
	  memcpy(&their_addr.sin_addr,he->h_addr_list[0],sizeof(struct in_addr));
