Broadcast

[Aurelian Radoaca]

Eu am un exemplu cu

#include <netinet/in.h> // uint16_t, sockaddr_in, htons(), htonl(),
INADDR_ANY, ntohs()
#include <arpa/inet.h> // inet_ntoa()

server.sin_family = AF_INET;
server.sin_port = htons(port);
server.sin_addr.s_addr = htonl(INADDR_ANY);
fprintf(stderr,"Server listening at %s, port %d\n",
inet_ntoa(server.sin_addr),ntohs(server.sin_port));

In rest pare la fel.
