java - Sockets- Client's Send not working -

in below code connection between c++ client , java server established using sockets. notified java server. send() in c++ client returning -1. can't seem grab problem.

struct sockaddr_in serv_addr; s_id = socket (pf_inet,sock_stream,0); if(s_id<0) {     printf("s_id error \n"); } else {     serv_addr.sin_family=af_inet;     serv_addr.sin_port =htons (9090);     serv_addr.sin_addr.s_addr = inet_addr ("127.0.0.1");     int c_check = connect (s_id,(struct sockaddr *) &serv_addr, sizeof (struct sockaddr));     if(c_check<0)     {         printf("b_check error \n");     }     else     {         intval temp(values);          char *char=new char[sizeof(temp)];         memcpy (&char, &temp, sizeof(temp));         int tempp;         tempp=send(s_id,char,sizeof(temp),0);         if(tempp==-1)         {             printf("nae gya\n");         }     } } close(s_id); 

the line

memcpy (&char, &temp, sizeof(temp)); 

should be

memcpy (char, &temp, sizeof(temp)); 

&char gives address of local variable points allocated memory. want copy temp allocated memory instead.

based on description of problem, i'd guess sizeof(temp) > sizeof(char*) write areas of stack in use other variables, including socket handle s_id gets corrupted.

note leak char @ present should add delete[] char after calling send.

alternatively, avoid allocating char @ if pass address of temp send

intval temp(values);  int tempp=send(s_id,&temp,sizeof(temp),0);
