Hi,
I want to transfer a file as it is via a socket...not read the file contents and send it.How can I do this?

I wrote the server and client programs.I'm sending data from server to client.
Server
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <errno.h>
#include <string.h>
#include <netdb.h>
#include <sys/types.h>
#include <netinet/in.h>
#include <sys/socket.h>
#define PORT 5432 // the port client will be connecting to
int main(int argc, char *argv[])
{
int sockfd, sockfd1, addrlen;
struct sockaddr_in srvr_addr,cli_addr; // server address information
FILE *fp=fopen("serv_1.mfcc","w");
char mfcc[16];
if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) == -1) {
perror("socket");
exit(1);
}
srvr_addr.sin_family = AF_INET; // host byte order
srvr_addr.sin_port = htons(PORT); // short, network byte order
srvr_addr.sin_addr.s_addr = inet_addr("127.0.0.1");
memset(&(srvr_addr.sin_zero), '\0', 8); // zero the rest of the struct
addrlen=sizeof(cli_addr);
bind(sockfd,(struct sockaddr *)&srvr_addr, sizeof(srvr_addr));
listen(sockfd,5);
sockfd1=accept(sockfd,(struct sockaddr *)&cli_addr,&addrlen);
while(1){
read(sockfd1,mfcc,16);
if(strcmp(mfcc,"fileend")==0)
{
break;
}
fprintf(fp,"%s",mfcc);
}
fclose(fp);
return 0;
}Client
#include <stdio.h>

{

if (connect(sockfd, (struct sockaddr *)&srvr_addr,
sizeof(struct sockaddr)) == -1) {
perror("connect");
exit(1);
}
while(!feof(fp)){
len=fread(mfcc,sizeof(char),15,fp);
mfcc[len]='\0';
write(sockfd,mfcc,len+1);
}
write(sockfd,"fileend",16);
fclose(fp);
close(sockfd);
return 0;
}my server side file is not getting created...im not sure why
