c++ - Socket Client always connects to localhost -

i have problem client seems connect localhost(127.0.0.1) though i'm passing address. consider: $ ./client 139.130.4.5 80

    if ( (sockfd = socket(af_inet, sock_stream, 0)) == -1 ){        error("opening socket");     }     if ( (server = gethostbyname(argv[1])) == null) {         fprintf(stderr,"error, no such host\n");         close(sockfd);         exit(0);     }     memset((char *) &serv_addr, 0, sizeof(serv_addr));     serv_addr.sin_family = af_inet;     memcpy((char *)server->h_addr, (char *)&serv_addr.sin_addr.s_addr, server->h_length);     serv_addr.sin_port = htons(portnum);      if (connect(sockfd,(struct sockaddr *) &serv_addr,sizeof(serv_addr)) == -1){         error("connect", sockfd);     } 

this results in connection localhost, though argv[1] 139.130.4.5 , portnum 80

in memcpy() function:

#include <string.h> void *memcpy(void *dest, const void *src, size_t n); 

the first argument destination, second source, instead of

memcpy((char *)server->h_addr, (char *)&serv_addr.sin_addr.s_addr, server->h_length); 

you should write

memcpy( &serv_addr.sin_addr.s_addr, server->h_addr, server->h_length);      // ^ adam pointed out, no (char*) here
