Error with bind()

Hi. I recently started learning network programming (from Beej's guide); here's a simple server I'm trying to make - its supposed to send a file to a specified port (both file_path and port number are provided from the terminal. I am getting a warning "server.c:78: warning: ‘client_address’ may be used uninitialized in this function" though it compiles. When I try to run it I get an error with bind(), but I'm not sure what's wrong with it.

Code:

#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netdb.h>
#include <string.h>
#include <assert.h>
#include <stdlib.h>

int main(int argc, char** argv)
{
       /*Return in case of insufficient input*/ 
	if(argc!=3)
	{
		fprintf(stderr,"Usage: server path_to_file port_number");
		return 1;
	}
	
		
	struct addrinfo hints,*res;
	
	memset(&hints,0,sizeof(hints));
       
        /*Setup hints for getaddrinfo*/
	hints.ai_family=AF_UNSPEC;
	hints.ai_flags=AI_PASSIVE;
	hints.ai_socktype=SOCK_STREAM;
	
	int status;
	
	status=getaddrinfo(NULL,argv[2],&hints,&res);
	if(status!=0)
	{
		fprintf(stderr,"Error with getaddrinfo");
		return 2;
	}
	
	int fd=socket(res->ai_family,res->ai_socktype,res->ai_protocol);
	assert(fd!=-1);
	
        /*Something wrong here?*/
	status=bind(fd,res->ai_addr,res->ai_addrlen);
	
	if(status!=0)
	{
		fprintf(stderr,"Error with bind");
		return 3;
	}
	
       /*Listen for incoming connections*/
	status=listen(fd,10);
	
	if(status!=0)
	{
		fprintf(stderr,"Error with listen");
		return 4;
	}
	
       /*accept*/
	struct sockaddr *client_address;
	socklen_t *client_addrlen;
	int new_fd=accept(fd,client_address,client_addrlen);
	assert(new_fd!=-1);
	
       /*Open file that is to be sent*/
	FILE  *file_to_send=fopen(argv[1],"r");
	assert(file_to_send!=NULL);
	
        /*Buffer for storing bytes*/
	void *buff=malloc(500);
	
	fread(buff,1,250,file_to_send);
	
	send(new_fd,buff,250,0);
	freeaddrinfo(res);
	fclose(file_to_send);
	
	return 0;
	
}

Thank you.

So look in errno to find out why!

I sort of got this thing working now..thanks Salem.
