Hi, i am coding a small c program in order to learn network programming: main(int argc, char *argv[]){ struct hostent *host; .... if((host=gethostbyname(argv[1])=NULL)){ perror("gethostbyname"); exit(-1);} /* now, i want to print out all the hostent struct information */ printf("struct hostent{\n"); printf("char *h_name: %s", host->h_name); printf("char **h_aliases:%s\n", host->h_length); printf("int h_addrtype: %d\n", host->h_addrtype); printf("int h_length: %d\n", host->h_length); printf("char **h_addr_list: %d\n", host->h_addr_list); } } This program core dumped, it may crash because i am trying to print an char array (h_addr_list, right?), I want to know how can i print all the information store in a struct hostent?, especiality the ip address. thanks __________________________________________________ Do You Yahoo!?
