How to send image through ethernet(tcp/ip)?

[cpplinuxnewbie]

HI,
i was working on a project in linux where tcp/ip communication is needed(i am using BSD sockets,calls like connect,send etc., ).
i send the data in the structure format. now i need to send an image, there comes the problem. i was new to this so can any one throw some light on how to send the image?
my guess were :
should i convert that Image into some binary data?? if so how can i do that?
or is there any way to send the image itself without any conversion?

Thnk in advance

The image is already binary data.

Just send it.

The image is already binary data
ok..
How to send ?? i mean Can any one give me the BSD socket system call with parameters to send the image .
for example to send message we use send(ssize_t send(int s, const void *buf, size_t len, int flags);) system call ..
In the same manner so that i can send the image directly.

@@Thanx in advance

Mmm, it sould like you need a sockets tutorial.

I've seen this one recomended, but I'd recomend reading a book like Stevens or Comer.

I think you should read the image into a buffer using read, then write the buffer to a socket descriptor, that's all, system calls may be used are as follows:

socket, connect(if you use UDP in your program, this is not necessary), read, write

#define LEN 1024

int fd;
int sockfd;
ssize_t nbytes;

sockfd = socket(AF_INET,SOCK_STREAM,0);

char buf[LEN];

memset(buf,0, LEN+1);

fd = open("yourImage",O_RDONLY);

//connecting or listening
...
//read

while((nbytes = read(fd,buf,LEN))>0){
write(sockdes,buf,nbytes);
}

@hittlle Thnk u .. i changed my design .. isntead of sending the image to the server.. i am trying to get the image from the client to server with FTP
