i am writing a client and server program
client program
main()
{
int sockfd,n;
char str[20];
struct sockaddr_in sock;
if ((sockfd=socket(AF_INET,SOCK_STREAM,0))<0)
{
perror("SOCKET ERROR");
}
bzero(&sock,sizeof(sock));
sock.sin_family=AF_INET;
sock.sin_port=7500;
sock.sin_addr.s_addr=inet_addr("192.127.137.251");
if(connect(sockfd,(struct sockaddr*)&sock,sizeof(sock))<0)
{
perror("CONNECT ERROR :");
}
strcpy(str,"i am here");
write(sockfd,(char *)str,strlrn(str)+1);
//close(sockfd);
socket program
main()
{
int sockfd,connfd,clientlen;
char str[20];
struct sockaddr_in sock,client;
if((sockfd=socket(AF_INET,SOCK_STREAM,0))<0)
{
perror("SOCKET ERROR ");
}
bzero(&sock,sizeof(sock));
sock.sin_family=AF_INET;
sock.sin_port=7500;
sock.sin_addr.s_addr=inet_addr("192.127.137.251");
if((bind(sockfd,(struct sockaddr*)&sock,sizeof(sock)))<0)
{
perror("BIND ERROR:");
}
listen(sockfd,3);
clientlen=sizeof(client);
if((connfd=accept(sockfd,(struct sockaddr*)&client,&clientlen))<0)
{
perror("CONNECTION ERROR :");
}
read(connfd,(char *)str,20);
printf("%s ",str);
close(connfd);
close(sockfd);
}
now the problem is i have to pass a integer or bool variable rather than string
how can i do this
